My daughter has had 3 greenish stools in the past 24 hours. I called the nurse and she said it was normal and fine, but she also told me to give my baby formula 2 days after I had delivered her since she hadn't had a BM since I brought her home from the hospital, so I am always leery of her advice. She has a cold from which she is on the upswing from, and she also had her 4 month vaccinations last Thurs, and she had run a temp for a few days and been pretty unhappy (esp. with a cold at the same time), but like I said, she has been feeling much better. Anyway, is this indeed normal for a 19 week old? Oh, and she seems to have been eating okay, even with the cold, so I wouldn't think it is a foremilk/hindmilk imbalance.
