My 12 week old has had a range of shades of green poo for the past week, from light to dark green to a very dark almost black poo the other day. Took her to the Docs who has sent a sample to the hospital, which is very worrying. I know green poo occasionally is not a big deal, but to continue for over a week? She is also starting to teeth, dribbling and chewing her hands, which might be causing her stomach to be upset. She has always fed a lot, every two hours still ( big baby, 10lbs 9oz born), but there has been no change in the way I breastfeed, so I am a bit baffled and very worried. Also, she is pooing a lot more, almost after every feed now. Doesn't seen poorly, no vomiting - has anyone else had this happen? New mumsnet person so please help!
