What should I do if I have a problem breastfeeding?
Contact your personal physician or someone professionally trained to assist with breastfeeding problems. Find a Lactation Consultant in your area, or contact a local La Leche League Leader.

Where can I get information on breastfeeding?
Contact your State Health Department, local WIC clinic, or local La Leche League affiliate. Download the US Department of Health and Human Services Blueprint for Action on Breastfeeding for more resources.

What are CDC's breastfeeding activities?
CDC's role is in research, surveillance, program evaluation and national policy development to support and promote breastfeeding. Many other U.S. Government agencies are currently working on issues related to breastfeeding. What's happening within the Federal government?

What percentage of women breastfeed their babies in the United States?
"Healthy People 2010" is a national initiative to increase health among Americans by the year 2010. That document uses the following 1998 percentages as baseline data for mothers who are breastfeeding at three different points in time:

In early postpartum period 64%
At 6 months 29%
At 1 year 16%

Rates of exclusive breastfeeding at 6 months of age, based on NHANES III data are: 

All infants 9.5%
Non-Hispanic White 10.9%
Non-Hispanic Black 4.2%
Mexican American 7.1%
Other 11.5%

Are there growth charts available to assess growth in breastfed infants?
Although there are no growth charts specifically for breastfed infants, the revised Centers for Disease Control Growth Charts, released on May 31, 2000 included breastfed babies in the reference population. These charts are recommended for all babies in the United States.

When should a baby start eating solid foods?
Exclusive breastfeeding is ideal nutrition and sufficient to support optimal growth and development for approximately the first 6 months after birth. The American Academy of Pediatrics (AAP) states that water, juice, and other foods are generally unnecessary in the first 6 months of life. Ask your pediatrician about what signs to look for, to show that your baby is ready to begin eating solid foods.

How long should a mother breastfeed?
The American Academy of Pediatrics (AAP) recommends that breastfeeding continue for at least 12 months, and thereafter for as long as mother and baby desire. The World Health Organization recommends continued breastfeeding up to 2 years of age or beyond.

What can happen if someone else's breastmilk is given to another child?
HIV and other serious infectious diseases can be transmitted through breastmilk. However, the risk of infection from a single bottle of breastmilk, even if the mother is HIV positive, is extremely small. For women who do not have HIV or other serious infectious diseases, there is little risk to the child who receives her breastmilk.

Does breast milk qualify as a "potential infectious fluid"?
No. CDC does not list human breastmilk as a body fluid to which universal precautions apply. Please read the CDC, MMWR, Mortality and Morbidity Weekly Report "Perspectives in Disease Prevention and Health Promotion Update: Universal Precautions for Prevention of Transmission of Human Immunodeficiency Virus, Hepatitis B Virus, and Other Bloodborne Pathogens in Health-Care Settings" or the American Academy of Pediatrics (AAP) 1995 Policy Statement on this issue for more information.

Should mothers who smoke or use prescription drugs breastfeed?
Most likely, yes. Most drugs likely to be prescribed to the nursing mother should have no effect on milk supply or on infant well-being. Mothers who smoke are encouraged to quit, however, breastmilk remains the ideal food for a baby even if the mother smokes.

The American Academy of Pediatrics (AAP) lists prescription and non-prescription drugs by their compatibility with breastfeeding.  Although nicotine may be present in breastmilk, adverse effects on the infant during breastfeeding have not been reported. AAP recognizes pregnancy and lactation as two ideal times to promote smoking cessation, but does not indicate that mothers who smoke should not breastfeed.

Is it safe for a hepatitis B carrier mother to breastfeed her baby?
Yes. A mother infected with hepatitis B virus does not need to avoid breastfeeding. She can begin breastfeeding her infant immediately after birth if she follows the recommendations of the Immunization Practices Advisory Committee.  Her infant should be vaccinated within 12 hours of birth with the second dose of vaccine given at 1 month of age, and the third dose at age 6 months.

Is it safe for a hepatitis C (HCV) positive mother to breastfeed?
Yes. Breastfeeding is not contraindicated for hepatitis C positive mothers. Transmission of hepatitis C through breastmilk has not been documented. More information is available through the CDC National Center for Infectious Diseases Hepatitis Web site in the Pregnancy and Breastfeeding portion of the Hepatitis C Frequently Asked Questions.

Is it safe for an HIV-infected mother to breastfeed?
HIV-infected women in the United States should not breastfeed or provide their breastmilk for the nutrition of any infants because of the risk of HIV transmission to the child. Read the American Academy of Pediatrics (AAP) 1995 Policy Statement for more information.

Can West Nile virus be transmitted through breastmilk?
Based on a recent case in Michigan, it appears that West Nile virus can be transmitted through breastmilk. However, the health benefits of breastfeeding are well established, and the risk of transmitting West Nile virus through breastfeeding is unknown. Therefore, these new findings do not suggest a change in breastfeeding recommendations.
Breastfeeding women who are ill or are having problems breastfeeding for any reason should consult their physician. The CDC, West Nile Virus Frequently Asked Questions."  and the Oct 4, 2002 MMWR, Morbidity and Mortality Weekly Report, answer questions concerning the West Nile virus and breastfeeding. 

Are silicone breast implants a risk for breastfed babies?
No. The American Academy of Pediatrics (AAP) latest statement on "Transfer of Drugs and Other Chemicals Into Human Milk" (Sept 2001),  states that it does NOT consider silicone breast implants to be a risk to the breastfeeding baby.

Many mothers successfully breastfeed their babies despite the presence of silicone breast implants. Find a Lactation Consultant in your area , or contact a local La Leche League Leader for support and assistance.

I have heard that chemicals that we are exposed to in the environment can be transmitted to infants through breastmilk. Should a mother still breastfeed her baby?
Yes. In spite of trace amounts of chemical residues found in breastmilk, breastfeeding is recommended worldwide. The benefits of breastfeeding, including better cognitive skills and better immune system, outweigh the possible risks of effects from environmental chemicals later in life. Human milk is the best nutrition for developing babies; therefore, mothers should breastfeed their infants. The American Academy of Pediatrics (AAP) Committee on Environmental Health has more information in their Handbook of Pediatric Environmental Health, chapter 16: Human Milk. 

I would like to donate breastmilk to someone who needs it. How can I donate breastmilk?
There are currently six milk banks operating in North America that are members of the Human Milk Banking Association of North America (HMBANA), which promulgates standards for treating and dispensing the milk. Just as donors of blood, organs and tissue are screened, so are women who donate their milk. Donor milk is pasteurized to kill bacteria and viruses, and then tested to ensure no bacteria are present. Banked milk is then frozen until needed, and rigid protocols ensure careful handling at each stage of processing and distribution. The milk is dispensed by prescription only.
HMBANA lists contact information for all North American regulated Milk Banks. Contact the milk bank nearest you for specific donation information.
