Girl, please tell me, how is the baby's stool after 9 days of breastfeeding? After the Meconium passed, it became yellow and mushy like puree. About a week ago (maybe up to 2 weeks), there were colic episodes, along with changes in stool color to green (sometimes with yellow streaks, like before). The stools have become more watery. The doctor came by, examined the baby and said everything was fine, but I am still worried if this is normal or not (it's my first child, so I don't know what's normal yet).
