Benefits to infants

Infants who are breastfed have a lower risk of:

• Asthma and severe lower respiratory diseases.
• Obesity.
• Type 1 diabetes.
• Acute otitis media (ear infections).
• Sudden infant death syndrome (SIDS).
• Gastrointestinal infections (diarrhea/vomiting).
• .

Benefits to mothers

Mothers who breastfeed their infants have a lower risk of:

• Breast cancer.
• Ovarian cancer.
• Type 2 diabetes.

Guidelines and recommendations

How long should a mother breastfeed?

Exclusive breastfeeding for about the first six months is recommended. The recommends continued breastfeeding while introducing appropriate complementary foods until children are 12 months old or older. The and the recommend continued breastfeeding along with introducing appropriate complementary foods for up to 2 years or longer.

Mothers should be encouraged to breastfeed their children for at least 1 year. The longer an infant is breastfed, the greater the protection from certain illnesses and long-term diseases. The longer a woman breastfeeds, the greater the benefits to her health as well.

When should a mother avoid breastfeeding?

Breast milk provides the best nutrition for most infants, including premature and sick newborns. However, there are rare exceptions when breast milk or breastfeeding is not recommended.

Only a few medications are not recommended while breastfeeding. Although many medications do pass into breast milk, most have little or no effect on milk supply or the infant's well-being. However, health care providers should always weigh the risks and benefits when prescribing medications to breastfeeding mothers. See the for information on drugs and other chemicals to which breastfeeding mothers may be exposed.

Growth assessment

How is growth assessed for breastfed infants?

In the United States, the WHO Growth Standard Charts are recommended for all infants and children from birth to age 2.1 These charts are modeled after the growth patterns of breastfed infants. In the first few months of life, healthy, breastfed infants typically gain weight faster than formula-fed infants. However, breastfed infants gain weight more slowly for the remainder of infancy even after introducing complementary foods.

For children 2 to 19 years of age, ÐÇ¿ÕÓéÀÖ¹ÙÍø and AAP recommend using the ÐÇ¿ÕÓéÀÖ¹ÙÍø Growth Reference Charts.

Growth Chart Training offers self-directed, interactive training courses.

Safety, preparation, and storage of breast milk

What if someone else’s breast milk is given to another child?

Very few illnesses are transmitted via breast milk. Learn what to do if an infant or child is mistakenly fed another woman's expressed breast milk.

Are special precautions needed for handling breast milk?

ÐÇ¿ÕÓéÀÖ¹ÙÍø does not list human breast milk as a body fluid to which universal precautions apply. Occupational exposure to human breast milk has not been shown to lead to transmission of HIV or hepatitis B infection. However, human breast milk has been implicated in transmitting HIV from mother to infant. Consequently, health care workers who are frequently exposed to breast milk, such as people working in human milk banks, may wear gloves as a precaution. See this Morbidity and Mortality Weekly Report.

What are human milk banks?

Nonprofit donor human milk banks have a long safety record in North America. All member banks of the (HMBANA) must operate under specific evidence-based guidelines. These guidelines require extensive testing and processing procedures including self-reported health information and a health statement from both the donor's and the infant's health care provider. Because most of the milk from milk banks is given to hospitalized and medically fragile infants, milk banks may not have enough to serve healthy infants at all times.

Breastfeeding and vaccines

Does breastfeeding during a child’s vaccines help with pain?

Women who are breastfeeding can breastfeed children ages 2 years or younger before, during, and after their child’s vaccination. Breastfeeding may decrease the child's pain several ways, including being held by the parent, feeling skin-to-skin contact, suckling, being distracted, and ingesting breast milk. Potential adverse events, such as gagging or spitting up, have not been reported. Alternatives to breastfeeding include bottle-feeding with expressed breast milk or formula throughout the child’s procedure.

Does breastfeeding after a child's rotavirus vaccine impact how well it works?

There is not enough evidence to suggest that breastfeeding negatively affects how well the rotavirus vaccine works. found that human milk from women who live in areas with endemic rotavirus contains antibodies that can neutralize live rotavirus vaccine virus. However, in licensing trials, in breastfed infants was comparable to that in non-breastfed infants.

ÐÇ¿ÕÓéÀÖ¹ÙÍø does not recommend restricting or discontinuing breastfeeding before or after a child receives the rotavirus vaccine. Breastfed infants should be vaccinated according to the same schedule as non-breastfed infants.

Pools and splash pads

Are there risks to breastfeeding in water?

No scientific study has examined the health and safety of breastfeeding babies in water. It is unlikely that breastfeeding in the water presents any more risks for babies and children than the risks of regular pool or splash pad use. These risks include swallowing water, exposure to swimming-related illnesses, issues regulating body temperature, and drowning. ÐÇ¿ÕÓéÀÖ¹ÙÍø is unaware of any risks to other swimmers related to breastfeeding in pool or splash pad water.
