Pregnancy Q&As

    Is it okay to continue breastfeeding throughout my pregnancy? I’ve heard rumors that breastfeeding can increase the risk of a miscarriage.

    There two main reasons people tell mothers they should wean their babies when they become pregnant: one, that breastfeeding puts you at an increased risk of miscarriage; and two, that a baby will suffer from lack of nutrients. Both claims are unsubstantiated. 

    In reality, it's hard to document why a miscarriage occurs. Unfortunately, 15 to 25 percent of all pregnancies end in miscarriage during the first three months. However, there are no studies that show breastfeeding increases this rate. 

    And there is no evidence that a baby whose mother is nursing will suffer from lack of nutrients if the mother's diet is healthy and balanced. (Millions of women nurse during pregnancy and give birth to healthy babies).
    There are, however, a few things women should know about breastfeeding during pregnancy:

    1. Nipple soreness is often associated with a new pregnancy so you may find you suddenly experience pain or discomfort while nursing.
    2. Fatigue is normal when you are in the early months of pregnancy, so if you feel tired while breastfeeding it's nothing unusual. Breastfeeding shouldn't make you feel more tired.
    3. Milk supply does decrease when you are pregnant. You can continue to breastfeed, but encourage your toddler to eat more solids and drink other liquids from a cup in order to make sure his nutritional needs are met.


    The choice to continue breastfeeding during pregnancy is totally up to you. Talk to your doctor about any concerns you have so you can make an informed decision you are comfortable with.
