  1. The decline in breastfeeding has been traced to

    THE HISTORY OF INFANT FEEDING

    The decline in breastfeeding has been traced to the social changes brought about by the industrial revolution [7]. In 1880, 95% of all infants were breastfed for two to four years, but as mothers began reporting breastfeeding difficulties, physicians blamed the stress of urban life and the "bad" human milk produced by urban women. These mothers, who were just learning about the germ theory of disease and anxious to protect their babies, began to gratefully rely on "scientific" food rather than that produced by their own bodies [5,8].

  2. Every state has passed legislation

    THE HISTORY OF INFANT FEEDING

    To protect breastfeeding women from harassment, states have passed laws that specifically address breastfeeding [15]. As of 2022, all 50 states have passed legislation specifically allowing women to breastfeed in any public or private location, and 31 states exempt breastfeeding from public indecency laws. Thirty states have passed laws related to breastfeeding in the workplace; 22 states exempt breastfeeding mothers from jury duty or allow jury service to be postponed; and 4 states (California, Illinois, Minnesota, Missouri) have implemented or encouraged the development of a breastfeeding awareness education campaign [15,16].

    A PARADIGM SHIFT IN SUPPORT OF BREASTFEEDING

    The American Academy of Pediatrics (AAP) policy statement Breastfeeding and the Use of Human Milk has established principles to guide pediatricians and other healthcare professionals in assisting women and children in the initiation and maintenance of breastfeeding [20]. It also has recognized the breastfed infant as the normal "gold" standard against which all research and recommendations for infant feeding should be made. This is a paradigm shift in American scientific thinking. The AAP has recommended exclusive breastfeeding for the infant's first six months of life, followed by continued breastfeeding for one year or longer as complementary foods are introduced. It also has recommended that [20,21,22]:

    • Parents be provided with complete, current information on the benefits and techniques of breastfeeding to ensure that decisions about feeding are fully informed

    • Peripartum policies and practices be developed to optimize the initiation and maintenance of breastfeeding

    • Healthy infants be placed in direct (skin-to-skin) contact with their mothers immediately after delivery and until the first feeding has been accomplished

    • Mother and infant sleep in proximity to one another to facilitate breastfeeding

    • Supplements (e.g., water, glucose water, formula, other fluids) not be given to breastfeeding infants unless medically indicated and ordered by a physician

    • Pacifiers not be used during the initiation of breastfeeding and then used only after breastfeeding is well established

    • Mothers be encouraged to have 8 to 12 feedings at the breast every 24 hours when the infant shows early signs of hunger (e.g., alertness, physical activity, mouthing, rooting)

    • Breastfeeding newborn infants be visited by a pediatrician or other healthcare professional by 3 to 5 days of age, and again at 2 to 3 weeks of age

    • All breastfed infants receive 400 IU of oral vitamin D drops daily beginning at hospital discharge and continuing until the daily consumption of vitamin D fortified formula or milk is 1,000 mL

    • Supplementary fluoride not be provided during the first 6 months of life (or at all if local water contains fluoride)

    • Direct breastfeeding be maintained, if at all possible, should hospitalization of the mother or infant be necessary; if not possible, pumping and feeding expressed milk should be encouraged

    A PARADIGM SHIFT IN SUPPORT OF BREASTFEEDING

    These statistics have generated concern among researchers and policy makers. All major medical societies in the United States, including the AAP, have recommended breastfeeding for as long as possible in infancy in order to improve childhood survival rates. The World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) guidelines have recommended extending breastfeeding for a minimum of two years. This recommendation is supported by research, which has shown a 21% decrease in U.S. infant mortality in breastfed infants [21]. Exclusive breastfeeding, or human milk feeding for a minimum of six months, provides the greatest level of protection against infantile illnesses.

The process for obtaining certification as a baby-friendly hospital has been established by UNICEF in collaboration with national governments worldwide. UNICEF's Ten Steps to Successful Breastfeeding has been the basis for evaluating hospitals and healthcare facilities for participation as a designated baby-friendly facility (Table 3). A 2000 statement by the United Nations (UN) regarding the "rights of the child" has been linked to the BFHI. The UN has stated that in order for hospitals with maternity units to be designated "child friendly" they must first fully implement the Ten Steps to Successful Breastfeeding and be accredited by WHO/UNICEF as baby friendly [42]. The Ten Steps to Successful Breastfeeding and the BFHI have been shown to be effective measures to increase breastfeeding initiation, duration, and exclusivity [43,44].

    • Increased respiratory illnesses (e.g., pneumonia, asthma, respiratory syncytial virus)

    • Otitis media (four times more prevalent in the ABM-fed infant)

    • Increased likelihood of childhood obesity

    • Increased risk of tooth decay (nursing bottle caries)

    • Risk of contaminated formula (either at the factory or at home) and ingestion of "allowable" amounts of insect parts, rat hairs, droppings, iron filings, and accidental excesses of chlorine and aluminum

    • Severe illness resulting from improper dilution or home additives

    • Increased allergies ranging from skin rashes to asthma

    • Increased risk of immune system disorders, such as:

      • Accelerates the development of celiac disease

      • Risk factor in adult onset of Crohn disease, ulcerative colitis, and rheumatoid arthritis

      • Risk factor (2% to 26%) in childhood onset insulin-dependent diabetes mellitus

      • Five- to eightfold risk of developing lymphomas in children younger than 15 years of age

      • May impair effectiveness of vaccines

  11. The total fat content of mature breast milk

    BREAST MILK

    Lipids provide 50% of the energy content in human milk and are its most variable component. The fat content of mature milk is approximately 3.8%. Fat content varies from one mother to another, from early to late lactation, from feeding to feeding, and within individual feedings. The total fat content varies from 22 g/L to 62 g/L and is independent of the frequency of breastfeeding. Maternal diet affects the constituents of the lipids but not the total fat content. When a mother's caloric intake is poor, fat is mobilized from maternal fat stores (primarily in the hips and thighs) [2]. The cholesterol level of breast milk remains constant despite manipulation of the mother's cholesterol intake. The lipid fraction of human milk provides essential fatty acids, which are important to proper brain growth. Tissues of breastfed and ABM-fed infants have demonstrated distinctly different plasma fatty acid compositions. Levels of fatty acids in lactating women have been shown to be low, suggesting that their transfer to breast milk occurs at the expense of the maternal stores [2].

  12. The immunoglobulin found in the highest concentration in human milk is

    BREAST MILK

    The immunoglobulin found in highest concentration in human milk is IgA. The secretory form of IgA (sIgA) lines the gut and respiratory system in adults and is the major component conferring passive immunity to the breastfed infant. It is both synthesized and stored in the breast, reaching levels up to 5 mg/mL in colostrum, then decreasing to 1 mg/mL in mature milk [2]. sIgA is stable in breast milk and not degraded by either gastric acid or digestive enzymes. It provides local immunity by building a lining on the walls of the intestinal tract, the oral pharynx, and the urinary tract, protecting the infant from infection by preventing invasion of organisms through the mucosa. sIgA fights disease without causing inflammation. IgA protects the infant from invasion but does not fully line the gut until the infant is about 6 months of age. It may take months before the infant can manufacture IgA. Bottle-fed infants have few means for battling ingested pathogens until they begin making IgA on their own [2]. Protection through passive immunity continues for as long as the infant is breastfed. A child's immune response is not fully developed until 5 years of age.

    BREAST MILK

    Colostrum, known as "liquid gold," is the first milk. It is a mixture of residual cells in the breast and newly formed milk. It is thick and yellow to orange in color with high ash content and higher concentrations of sodium, potassium, chloride, protein, fat-soluble vitamins, and minerals than mature milk. Colostrum also is rich in antibodies that protect the newborn. It has an important laxative effect on the infant bowel that assists in the emptying of meconium. This is important because the retention of meconium may contribute to neonatal jaundice due to reabsorption of its bilirubin content [118].

  14. Stage II lactogenesis occurs

    BREAST MILK

    Stage II of lactogenesis begins with the sudden withdrawal of pregnancy hormones around the time of delivery; it may be defined as the time of copious milk secretion. Stage II is marked by increases in blood flow, oxygen, and glucose as well as sharply increased concentrations of citrate in the breast [122]. The breasts will begin to produce milk independent of infant suckling.

  15. Although prolactin levels rise during pregnancy, milk production is blocked by

    BREAST MILK

    Progesterone antagonism from the placenta enables the prolactin level to rise without subsequent milk production. Progesterone interferes with prolactin's activity on the cell receptor sites in the alveoli of the breast. With the birth of the placenta and the sudden drop in the pregnancy hormones progesterone and estrogen, the elevated prolactin level, in addition to the presence of insulin and cortisol, brings in the milk supply. Prolactin is released in pulses directly related to stimulation of the areola or breast. Prolactin levels decrease as lactation is established, but nursing stimulates prolactin release from the pituitary, which promotes continued milk production [1,2,124,125,126].

    BREAST MILK

    The prolactin receptor site theory has raised concern over progesterone-laden birth control methods when they are started within days of the birth. Medroxyprogesterone acetate (Depo-Provera) shots are sometimes given immediately postpartum, while the mother is still in the hospital. If progesterone is an antagonist to prolactin, logic dictates that progesterone shots, implants, and pills can inhibit early establishment of milk production [1]. Detectable amounts of Depo-Provera have been identified in the milk of mothers receiving the drug; however, it does not appear to adversely affect milk composition, quality, or amount [127]. Therefore, the Academy of Breastfeeding Medicine recommends that clinicians advise women that hormonal contraceptive methods may decrease milk supply, especially in the early postpartum period. Additionally, hormonal methods may be discouraged in some circumstances, such as [128]:

    • Existing low milk supply or history of lactation failure

    • History of breast surgery

    • Multiple birth (twins, triplets)

    • Preterm birth

    BREAST MILK

    It is important to note that the breast never truly empties and that the rate of milk production depends on the rate of milk removal (i.e., the more milk removed by infant demand, the greater the milk production). Research has demonstrated that each breast makes milk slowly or quickly depending on how full or empty it is. A full breast produces milk slowly; an empty breast produces milk more quickly. Therefore, when the mother's breast seems emptiest, it is making milk the fastest. If baby is hungry and nurses vigorously, leaving the breast relatively empty, production speeds up. If baby does not take much milk while feeding, production slows down. Thus, baby's appetite controls mother's milk production. Assuring that baby has access to the breast when hungry allows the baby to regulate milk production [1,2].

  18. Studies into breast storage capacity show that what type of feeding is best for baby and the mother's milk supply?

    BREAST MILK

    Research has indicated that each breast has its own individualized maximum storage capacity, which is not related to breast size. However, mothers with larger breasts have greater storage capacity (the difference between maximum and minimum breast volumes during a 24-hour period) and, as a result, greater flexibility in feeding intervals. Women with smaller breasts can produce as much milk as women with larger breasts, but they must breastfeed more often [2]. This helps explain why cue feeding, rather than strict scheduling, is best for baby and for the mother's milk supply.

    BREAST MILK

    If the breasts are not signaled by a suckling infant or breast stimulation within the first 24 to 48 hours postpartum, the result is alveolar distention, tissue congestion, and destruction of alveolar tissue. Distended lactational tissue and tissue congestion may prevent the appropriate hormones from reaching the breast and producing the desired effect of milk synthesis and milk ejection. Some mothers develop a fever if excessive engorgement occurs. A fever as high as 100°F accompanying engorgement in the early postpartum period may be mistaken for postpartum infection. Unrelieved engorgement and over-distention of the alveoli may cause some alveoli to rupture, resulting in partial involution of the breast. Subsequently, complete involution of the breasts may occur in as little as six hours in unrelieved engorgement [131].

    BREAST ANATOMY AND DEVELOPMENT

    The breast is composed of glandular tissue, fibrous tissue, and adipose (fatty) tissue. The relative proportion of each type of tissue changes with a woman's age, menstrual cycle, pregnancy, and nutritional status. The significant structures of the adult female breast include (Figure 1) [2,14,122,133]:

    • Alveolus (acinus) cells: Where milk is produced, stored, and secreted

    • Myoepithelial cells: Surround the alveoli and contract so milk is forced into the ductules

    • Ductules: Filter out milk from the alveoli

    • Nipple (mammary papilla): Functions as a nozzle for delivery of milk; is the most sensitive to tactile stimulation and pain

    • Nipple openings

    • Areola: The darker portion behind the nipple; may vary widely in size and color

    • Montgomery glands or tubercles (areolar glands): Secrete oils that lubricate the nipple; may be antibacterial

    • Lobe: The branching network of the above structures; each breast contains approximately 20, ending in the nipple

    Women may develop breast lumps at any time. Approximately 29% of cases of breast cancer occurs in women younger than 45 years of age [140]. The average patient is between 32 and 38 years of age [141]. Breast cancer is the most common cancer in pregnant and postpartum women, occurring in about 1 in 3,000 pregnant women; however, this percentage may increase as more women delay childbearing until their mid- to late-30s [141,142,143,144]. The breast changes that accompany pregnancy and lactation often make the mother aware of a lump that she has not felt before. Pregnant and lactating breasts are dense and lumpy. Women may delay treatment because they believe the lump is a disorder of lactation that will remedy itself. Inflammatory breast cancer, the most lethal of localized advanced cancers, often mimics mastitis; however, there are no systemic symptoms [143].

    HIV infection: Although the risk of postpartum HIV infection of the infant remains unclear, studies have indicated that vertical transmission of HIV through breast milk is possible. The AAP has recommended that women who test positive for HIV not breastfeed in order to help prevent transmission of the virus to their infants. The CDC also has recommended that any woman with known HIV infection should be informed about the risks of HIV transmission through breast milk and counseled not to breastfeed. The WHO guidelines have indicated that when the mother is HIV infected, the additional risk of the infant dying if not breast-fed should be compared to the infant's risk of becoming HIV infected through breastfeeding. The mother who is HIV positive and wants her infant to receive human milk may choose to either pump her own milk and have it pasteurized at a local milk bank or hospital or obtain milk from a breast milk bank.

    Breast cancer: The woman with active breast cancer requires treatment for herself. Women with a history of breast cancer should not be prohibited from breastfeeding. However, the infant should be monitored for appropriate growth, as radiation to the breast causes destruction of the milk-producing glands.

    Active hepatitis B infection: Hepatitis B transmission through breastfeeding has not been reported. Infants born to hepatitis B-infected mothers should be immunized with hepatitis B immune globulin immediately after birth, plus given a first dose of human hepatitis B vaccine within 12 hours of birth. With appropriate follow-up immunizations, the baby may nurse.

    Hepatitis C: Most patients with hepatitis C are asymptomatic with no traceable transmission route. The greatest risk is chronic active hepatitis C. Infection through breast milk appears to be infrequent.

However, these agents also may affect the course of labor, the neurobehavioral state of the neonate, and the initiation of breastfeeding. Unmedicated birth followed by immediate skin-to-skin contact between mother and infant leads to the highest likelihood of baby-led breastfeeding initiation. Difficult, medicated labors may lower the rate of breastfeeding success due to the effects on the infant, including depressed or delayed suckling (Table 8) [167,168,169].

    HOSPITAL ROUTINES THAT SUPPORT LACTATION

    Breastfeeding can be unconsciously sabotaged by hospital routines. Newborn policies can have serious effects on lactation and may contribute to maternal engorgement and routine assignment of any cesarean section baby to the nursery for several hours after birth. In addition to ensuring skin-to-skin contact between mother and infant immediately following birth, nursery and postpartum routines that support lactation include [1,2,21,200,202,203,204,205,206,207,208]:

    • Support the mother's decision to breastfeed. When direct breastfeeding is not possible, expressed human milk should be provided. The newborn should have access to the breast around the clock. The baby will need 10 to 12 feedings per day during the first week of life. Both mother and baby will get off to the best possible start breastfeeding if the baby remains with the mother (rooming-in). Breastfeeding mothers should be advised to feed at night as well.

    • Avoid take-over behavior. The mother is the expert where her baby is concerned. Some hospitals have instituted a "hands-off technique" that emphasizes ways to teach mothers without actually doing it for them.

    • Minimize or modify the course of maternal medications that may alter the infant's alertness and feeding behavior.

    • Avoid procedures that may interfere with breastfeeding or traumatize the infant (e.g., unnecessary, excessive, over-vigorous suctioning).

    • Avoid giving supplements (e.g., water, glucose water, formula, other fluids) to breastfeeding infants unless physician ordered and medically indicated; normal, healthy newborns do not need supplementation. Additionally, some infants may have breastfeeding difficulties from as little as one bottle. The baby's initial recognition of the mother involves the distinctive features of the mother's nipple. If an infant who is learning to breastfeed receives supplementation, either from a bottle or a pacifier, the nipple-recognition signals become mixed, resulting in what has been referred to as "nipple confusion." Although the existence of nipple confusion has not been universally accepted, studies have shown that supplementation and the introduction of a foreign nipple are associated with decreased rates of continued breastfeeding.

    • Avoid pacifier use during initiation of breastfeeding and until after it has been well established.

The nipple remains sensitive for a few days after delivery. Most mothers report mild latch-on pain in the first week that disappears after the first 30 seconds of a feeding. Pain beyond the first minute or so of nursing is a sign of improper latching and should be immediately corrected. Instruct the mother to take a deep breath and release it slowly. If pain persists, she should detach the baby by inserting her finger in the corner of his or her mouth to break the latch and try again. Baby may need to go on and off the breast several times before the latch is correct [209].

    THE LATCH-ON PROCESS

    Following the initial quiet alert stage after birth, baby goes into a deep sleep, recovering from the rigors of labor. Deep sleep is followed by increased wakefulness and increased nursing demands called "cluster feeding." Mothers often interpret cluster feeding as an indication that their baby is not getting enough milk [2]. This is the prime time during which mothers request supplemental bottles. Anticipatory guidance about these episodes can prevent the mother from assuming her milk is inadequate and giving supplemental bottles. Assure the mother that cluster feeding is normal and that it is actually a series of mini-feedings that are often followed by another period of deep sleep. Mother should be encouraged to catch up on her own sleep between cluster feedings [2].

  34. Possible warning signs of primary failure of lactogenesis include all of the following, EXCEPT:

    COMPLICATIONS

    Although primary failure of lactogenesis is rare, warning signs that require watching include [1,2]:

    • Acute illness in the mother

    • Severe toxemia of pregnancy (pregnancy-induced hypertension) and HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count)

    • Severe hemorrhage (hemoglobin level below 7) and/or anemia

    • Sheehan syndrome (infarct of the pituitary associated with severe postpartum hemorrhage or shock)

    • Any mechanical change in the breast (reduction or augmentation surgery)

    • Primary glandular insufficiency. Provisions should be made for the babies of these mothers to be followed closely for weight gain after hospital discharge

    COMPLICATIONS

    Jaundice in the newborn is the result of a normal elevation of unconjugated bilirubin and often referred to as "physiologic jaundice of the newborn" [2,221]. This is a common clinical condition that occurs in roughly two-thirds of all newborns. It disappears in about one week in the ABM-fed infant but may persist for several weeks in the breastfed infant. This pattern is known as "breast milk jaundice" [2,230].

  36. Improper breastfeeding ("starvation") jaundice

    COMPLICATIONS

    Because breast milk jaundice is a prolongation of neonatal jaundice, it is typically identified after the infant has been discharged from the hospital. "Starvation jaundice," however, may be seen as early as the first few days after birth, although not before 24 hours. Starvation jaundice has been observed in infants who have not established adequate feedings. Whether due to maternal or neonatal factors, infants who have not established adequate breastfeeding should not be discharged. Breastfeeding evaluation, encouragement and training for the mother (e.g., positioning, latching), and continuation of breastfeeding to restore fluid and caloric intake should occur [2]. Poor caloric intake and/or dehydration associated with inadequate breastfeeding may contribute to the development of hyperbilirubinemia. Increasing the frequency of nursing decreases the likelihood of subsequent significant hyperbilirubinemia in breastfed infants [222].

  37. Nipple creams generally are

    BREASTFEEDING DEVICES

    Numerous studies have shown that breast/nipple creams do not assist in the prevention or healing of sore nipples. Additionally, many ingredients in breast/nipple cream preparations may be hazardous to the newborn [265]. Breast and nipple creams generally are not recommended for the nursing mother by lactation consultants [2]. Table 12 is a brief list of some commonly used agents and comments on each.

  38. Which of the following symptoms of postpartum depression requires emergency attention?

    BREASTFEEDING: THE EARLY MONTHS

    Unfortunately, many women fail to recognize the signs and symptoms of PPD, and when they do, they fail to seek treatment [272]. Women with a history of prior depression, panic disorder, obsessive compulsive disorder, marital problems, premature delivery, premenstrual syndrome, or prior PPD are at highest risk for developing PPD. Additional risk factors include lack of social support, lower income and education, single status, life stress, and unintended pregnancy [271]. The American Academy of Family Physicians has listed the following as warning signs of PPD [273]:

    • Persistent feelings of sadness and crying

    • Having little desire to eat; significant weight gain or loss

    • Irritability, anxiety, restlessness, insomnia

    • Inability to find pleasure/interest in life; having little interest in the newborn

    • Feeling exhausted, having no motivation to get things done

    • Suicidal ideation or thoughts of harming the baby (requires emergency attention)

  40. Certified lactation consultants

    SUPPORT FOR THE BREASTFEEDING COUPLE

    A lactation consultant is a formally trained breastfeeding expert. The International Lactation Consultant Association (ILCA) is the professional association for International Board Certified Lactation Consultants (IBCLCs) and other healthcare professionals who care for breastfeeding families. An IBCLC is a healthcare professional who specializes in the clinical management of breastfeeding. They are certified by the International Board of Lactation Consultant Examiners, under the direction of the U.S. National Commission for Certifying Agencies. IBCLCs work worldwide in a variety of healthcare settings [283].

    Consultants come from a variety of backgrounds, and include nurses, educators, and individuals who have counseled breastfeeding women for many years. Hospitals often have a lactation consultant associated with their maternity unit. Training and approach to difficulties may vary slightly among consultants. The one thing that all lactation consultants have in common is the sincere desire to help women toward a successful breastfeeding experience.
