Breastfeeding is widely recognized by the Centers for Disease Control and Prevention as the best source of nutrition for most infants. Not only does breast milk provide essential nutrients and antibodies that help protect babies from illnesses, but it also lowers the risk of sudden unexpected infant death (SUID)—formerly known as sudden infant death syndrome (SIDS)—allergies, asthma, diabetes, and childhood obesity.

The benefits extend to mothers as well. Breastfeeding is cost-effective, saves time, and helps the uterus return to its prepregnancy size. It also fosters a close bond between mother and baby and reduces the risk of type 2 diabetes, breast cancer, ovarian cancer, high blood pressure, and heart disease. Despite these advantages, many myths and misconceptions about breastfeeding persist. The following explores some common myths and the facts behind them to help parents make informed choices.

Myth 1: Formula is just as good as breastmilk.

Breastmilk contains antibodies, hormones, and nutrients that are uniquely tailored to your baby’s needs and help protect against infections and diseases. Formula provides nutrition but does not offer the same immune benefits.

Myth 2: You can’t breastfeed if you have small breasts.

Breast size does not affect milk production. Milk supply depends on how often and effectively your baby nurses, not breast size.

Myth 3: Breastfeeding makes your breasts sag.

It is pregnancy, not breastfeeding, that causes most changes in breast shape. Things like your age, genetics, and how many times you have been pregnant also play a big role.

Myth 4: Breastfeeding moms should be on a special diet.

Most people who breastfeed do not need a special diet. Eating a balanced, healthy diet and staying hydrated is recommended, but breastmilk quality remains high even if your diet is not perfect.

Myth 5: You can’t get pregnant while breastfeeding.

Breastfeeding can delay the return of fertility, especially in the first 6 months if you are exclusively breastfeeding. However, it is still possible to get pregnant, so contraception is recommended if you wish to avoid pregnancy.

Myth 6: You should stop breastfeeding if you get sick.

In most cases, you can continue breastfeeding when sick. Your body produces antibodies that help protect your baby from illness. Always consult your health-care provider if you are unsure or have concerns.

Myth 7: If you go back to work or school, you need to wean your baby off breast milk.

Many mothers continue breastfeeding after returning to work or school by pumping milk and storing it for later. Federal law protects your right to pump at work.

Myth 8: If the baby is crying, that means you are not producing enough milk.

Babies cry for many reasons, not just hunger. Crying does not necessarily mean low milk supply. Signs of adequate milk intake include regular wet diapers and steady weight gain.

Myth 9: Breastfeeding parents get less sleep than formula-feeding parents.

Studies show breastfeeding parents may get more sleep overall, as breastfeeding releases hormones that promote relaxation and sleep, and nighttime feeding can be quicker.

Myth 10: You can’t take medication if you breastfeed.

Many medications are safe to take while breastfeeding. Always check with your health-care provider or a lactation consultant before starting any medication.
