Considerable advances have occurred in recent years in the scientific knowledge of the benefits of breastfeeding, the mechanisms underlying these benefits, and in the clinical management of breastfeeding. This policy statement on breastfeeding replaces the 1997 policy statement of the American Academy of Pediatrics and reflects this newer knowledge and the supporting publications. The benefits of breastfeeding for the infant, the mother, and the community are summarized, and recommendations to guide the pediatrician and other health care professionals in assisting mothers in the initiation and maintenance of breastfeeding for healthy term infants and high-risk infants are presented. The policy statement delineates various ways in which pediatricians can promote, protect, and support breastfeeding not only in their individual practices but also in the hospital, medical school, community, and nation.


Key Words: breast • breastfeeding • breast milk • human milk • lactation

Extensive research using improved epidemiologic methods and modern laboratory techniques documents diverse and compelling advantages for infants, mothers, families, and society from breastfeeding and use of human milk for infant feeding.1 These advantages include health, nutritional, immunologic, developmental, psychologic, social, economic, and environmental benefits. In 1997, the American Academy of Pediatrics (AAP) published the policy statement Breastfeeding and the Use of Human Milk.2 Since then, significant advances in science and clinical medicine have occurred. This revision cites substantial new research on the importance of breastfeeding and sets forth principles to guide pediatricians and other health care professionals in assisting women and children in the initiation and maintenance of breastfeeding. The ways pediatricians can protect, promote, and support breastfeeding in their individual practices, hospitals, medical schools, and communities are delineated, and the central role of the pediatrician in coordinating breastfeeding management and providing a medical home for the child is emphasized.3 These recommendations are consistent with the goals and objectives of Healthy People 2010,4 the Department of Health and Human Services' HHS Blueprint for Action on Breastfeeding,5 and the United States Breastfeeding Committee's Breastfeeding in the United States: A National Agenda.6

This statement provides the foundation for issues related to breastfeeding and lactation management for other AAP publications including the New Mother's Guide to Breastfeeding7 and chapters dealing with breastfeeding in the AAP/American College of Obstetricians and Gynecologists Guidelines for Perinatal Care,8 the Pediatric Nutrition Handbook,9 the Red Book,10 and the Handbook of Pediatric Environmental Health.11

Child Health Benefits
Human milk is species-specific, and all substitute feeding preparations differ markedly from it, making human milk uniquely superior for infant feeding.12 Exclusive breastfeeding is the reference or normative model against which all alternative feeding methods must be measured with regard to growth, health, development, and all other short- and long-term outcomes. In addition, human milk-fed premature infants receive significant benefits with respect to host protection and improved developmental outcomes compared with formula-fed premature infants.1322 From studies in preterm and term infants, the following outcomes have been documented.

Infectious Diseases
Research in developed and developing countries of the world, including middle-class populations in developed countries, provides strong evidence that human milk feeding decreases the incidence and/or severity of a wide range of infectious diseases23 including bacterial meningitis,24,25 bacteremia,25,26 diarrhea,2733 respiratory tract infection,22,3340 necrotizing enterocolitis,20,21 otitis media,27,4145 urinary tract infection,46,47 and late-onset sepsis in preterm infants.17,20 In addition, postneonatal infant mortality rates in the United States are reduced by 21% in breastfed infants.48

Other Health Outcomes
Some studies suggest decreased rates of sudden infant death syndrome in the first year of life4955 and reduction in incidence of insulin-dependent (type 1) and non–insulin-dependent (type 2) diabetes mellitus,5659 lymphoma, leukemia, and Hodgkin disease,6062 overweight and obesity,19,6370 hypercholesterolemia,71 and asthma3639 in older children and adults who were breastfed, compared with individuals who were not breastfed. Additional research in this area is warranted.

Neurodevelopment
Breastfeeding has been associated with slightly enhanced performance on tests of cognitive development.14,15,7280 Breastfeeding during a painful procedure such as a heel-stick for newborn screening provides analgesia to infants.81,82

Maternal Health Benefits
Important health benefits of breastfeeding and lactation are also described for mothers.83 The benefits include decreased postpartum bleeding and more rapid uterine involution attributable to increased concentrations of oxytocin,84 decreased menstrual blood loss and increased child spacing attributable to lactational amenorrhea,85 earlier return to prepregnancy weight,86 decreased risk of breast cancer,8792 decreased risk of ovarian cancer,93 and possibly decreased risk of hip fractures and osteoporosis in the postmenopausal period.9496

Community Benefits
In addition to specific health advantages for infants and mothers, economic, family, and environmental benefits have been described. These benefits include the potential for decreased annual health care costs of $3.6 billion in the United States97,98; decreased costs for public health programs such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)99; decreased parental employee absenteeism and associated loss of family income; more time for attention to siblings and other family matters as a result of decreased infant illness; decreased environmental burden for disposal of formula cans and bottles; and decreased energy demands for production and transport of artificial feeding products.100102 These savings for the country and for families would be offset to some unknown extent by increased costs for physician and lactation consultations, increased office-visit time, and cost of breast pumps and other equipment, all of which should be covered by insurance payments to providers and families.

Although breastfeeding is optimal for infants, there are a few conditions under which breastfeeding may not be in the best interest of the infant. Breastfeeding is contraindicated in infants with classic galactosemia (galactose 1-phosphate uridyltransferase deficiency)103; mothers who have active untreated tuberculosis disease or are human T-cell lymphotropic virus type I–or II–positive104,105; mothers who are receiving diagnostic or therapeutic radioactive isotopes or have had exposure to radioactive materials (for as long as there is radioactivity in the milk)106108; mothers who are receiving antimetabolites or chemotherapeutic agents or a small number of other medications until they clear the milk109,110; mothers who are using drugs of abuse ("street drugs"); and mothers who have herpes simplex lesions on a breast (infant may feed from other breast if clear of lesions). Appropriate information about infection-control measures should be provided to mothers with infectious diseases.111

In the United States, mothers who are infected with human immunodeficiency virus (HIV) have been advised not to breastfeed their infants.112 In developing areas of the world with populations at increased risk of other infectious diseases and nutritional deficiencies resulting in increased infant death rates, the mortality risks associated with artificial feeding may outweigh the possible risks of acquiring HIV infection.113,114 One study in Africa detailed in 2 reports115,116 found that exclusive breastfeeding for the first 3 to 6 months after birth by HIV-infected mothers did not increase the risk of HIV transmission to the infant, whereas infants who received mixed feedings (breastfeeding with other foods or milks) had a higher rate of HIV infection compared with infants who were exclusively formula-fed. Women in the United States who are HIV-positive should not breastfeed their offspring. Additional studies are needed before considering a change from current policy recommendations.

Certain conditions have been shown to be compatible with breastfeeding. Breastfeeding is not contraindicated for infants born to mothers who are hepatitis B surface antigen–positive,111 mothers who are infected with hepatitis C virus (persons with hepatitis C virus antibody or hepatitis C virus-RNA–positive blood),111 mothers who are febrile (unless cause is a contraindication outlined in the previous section),117 mothers who have been exposed to low-level environmental chemical agents,118,119 and mothers who are seropositive carriers of cytomegalovirus (CMV) (not recent converters if the infant is term).111 Decisions about breastfeeding of very low birth weight infants (birth weight <1500 g) by mothers known to be CMV-seropositive should be made with consideration of the potential benefits of human milk versus the risk of CMV transmission.120,121 Freezing and pasteurization can significantly decrease the CMV viral load in milk.122

Tobacco smoking by mothers is not a contraindication to breastfeeding, but health care professionals should advise all tobacco-using mothers to avoid smoking within the home and to make every effort to wean themselves from tobacco as rapidly as possible.110

Breastfeeding mothers should avoid the use of alcoholic beverages, because alcohol is concentrated in breast milk and its use can inhibit milk production. An occasional celebratory single, small alcoholic drink is acceptable, but breastfeeding should be avoided for 2 hours after the drink.123

For the great majority of newborns with jaundice and hyperbilirubinemia, breastfeeding can and should be continued without interruption. In rare instances of severe hyperbilirubinemia, breastfeeding may need to be interrupted temporarily for a brief period.124

Data indicate that the rate of initiation and duration of breastfeeding in the United States are well below the Healthy People 2010 goals (see Table 1). 4,125 Furthermore, many of the mothers counted as breastfeeding were supplementing their infants with formula during the first 6 months of the infant's life.5,126 Although breastfeeding initiation rates have increased steadily since 1990, exclusive breastfeeding initiation rates have shown little or no increase over that same period of time. Similarly, 6 months after birth, the proportion of infants who are exclusively breastfed has increased at a much slower rate than that of infants who receive mixed feedings.125 The AAP Section on Breastfeeding, American College of Obstetricians and Gynecologists, American Academy of Family Physicians, Academy of Breastfeeding Medicine, World Health Organization, United Nations Children's Fund, and many other health organizations recommend exclusive breastfeeding for the first 6 months of life.{ddagger}2,127130 Exclusive breastfeeding is defined as an infant's consumption of human milk with no supplementation of any type (no water, no juice, no nonhuman milk, and no foods) except for vitamins, minerals, and medications.131 Exclusive breastfeeding has been shown to provide improved protection against many diseases and to increase the likelihood of continued breastfeeding for at least the first year of life.

  1. Pediatricians and other health care professionals should recommend human milk for all infants in whom breastfeeding is not specifically contraindicated and provide parents with complete, current information on the benefits and techniques of breastfeeding to ensure that their feeding decision is a fully informed one.147149
  2. Peripartum policies and practices that optimize breastfeeding initiation and maintenance should be encouraged.
  3. Healthy infants should be placed and remain in direct skin-to-skin contact with their mothers immediately after delivery until the first feeding is accomplished.156158
  4. Supplements (water, glucose water, formula, and other fluids) should not be given to breastfeeding newborn infants unless ordered by a physician when a medical indication exists.148,162165
  5. Pacifier use is best avoided during the initiation of breastfeeding and used only after breastfeeding is well established.166168
  6. During the early weeks of breastfeeding, mothers should be encouraged to have 8 to 12 feedings at the breast every 24 hours, offering the breast whenever the infant shows early signs of hunger such as increased alertness, physical activity, mouthing, or rooting.170
  7. Formal evaluation of breastfeeding, including observation of position, latch, and milk transfer, should be undertaken by trained caregivers at least twice daily and fully documented in the record during each day in the hospital after birth.174,175
  8. All breastfeeding newborn infants should be seen by a pediatrician or other knowledgeable and experienced health care professional at 3 to 5 days of age as recommended by the AAP.124,176,177
  9. Breastfeeding infants should have a second ambulatory visit at 2 to 3 weeks of age so that the health care professional can monitor weight gain and provide additional support and encouragement to the mother during this critical period.
  10. Pediatricians and parents should be aware that exclusive breastfeeding is sufficient to support optimal growth and development for approximately the first 6 months of life{ddagger} and provides continuing protection against diarrhea and respiratory tract infection.30,34,128,178184 Breastfeeding should be continued for at least the first year of life and beyond for as long as mutually desired by mother and child.185
  11. All breastfed infants should receive 1.0 mg of vitamin K1 oxide intramuscularly after the first feeding is completed and within the first 6 hours of life.199
  12. All breastfed infants should receive 200 IU of oral vitamin D drops daily beginning during the first 2 months of life and continuing until the daily consumption of vitamin D-fortified formula or milk is 500 mL.201
  13. Supplementary fluoride should not be provided during the first 6 months of life.202
  14. Mother and infant should sleep in proximity to each other to facilitate breastfeeding.203
  15. Should hospitalization of the breastfeeding mother or infant be necessary, every effort should be made to maintain breastfeeding, preferably directly, or pumping the breasts and feeding expressed milk if necessary.

Although economic, cultural, and political pressures often confound decisions about infant feeding, the AAP firmly adheres to the position that breastfeeding ensures the best possible health as well as the best developmental and psychosocial outcomes for the infant. Enthusiastic support and involvement of pediatricians in the promotion and practice of breastfeeding is essential to the achievement of optimal infant and child health, growth, and development.
