Question
Breast-feeding while pregnant: Is it safe?
Is it safe to continue breast-feeding if I'm pregnant with another child?
Answer
from Roger W. Harms, M.D.
Generally, it's possible to safely continue breast-feeding while pregnant — as long as you're careful about eating a healthy diet and diligently drinking plenty of fluids. There's an important caveat, however. Breast-feeding can trigger mild uterine contractions. Although these contractions aren't a concern during an uncomplicated pregnancy, your health care provider may discourage breast-feeding while pregnant if you have a history of preterm labor.
If you're considering breast-feeding while pregnant, be prepared for changes your nursing child might notice. Although breast milk continues to be nutritionally sound throughout pregnancy, the content of your breast milk will change — which may affect the way your milk tastes. In addition, your milk production is likely to decrease as your pregnancy progresses. These factors could lead your nursing child to wean on his or her own before the baby is born.
Your comfort may also be a concern. During pregnancy, nipple tenderness and breast soreness are common. The discomfort may intensify while breast-feeding. Pregnancy-related fatigue may pose challenges as well. If you want to continue breast-feeding while pregnant — or breast-feed both the baby and the older child after delivery — you may need additional support from loved ones or other close contacts. Also check with your health care provider about taking supplemental prenatal vitamins.
