Anyone breastfeed while pregnant? I keep hearing its ok, go ahead and wait to wean her but I've also heard that it can cause miscarriages. Any thoughts?

I have and it didn't cause any problems. The reason "they" say it may cause miscarriages is because nipple stimulation can cause uterine contractions. I do know that lots of women breastfeed throughout their pregnancies without a problem. How old is your nursing child? If he or she is still exclusively breastfeeding you need to watch to make sure your milk supply stays up. Your hormones may cause your milk to drop. It may also taste different. The baby may wean on their own for these reasons.
