I have a baby fainter that is 1 week old today. I have mentioned in another thread that she was born so weak that she could not stand up for 3 days. She has seemed to be getting stronger and Sunday could actually stand up and nurse all by herself. I keep her in the house except to nurse her mother because she has a cold and is very frail. Last night she was crying and seemed to have gas or a belly ache. This morning when she got up, she pooped bloody goo. She was hungry and nursed her mother and played a little but she has had 6 bloody stools so far that I have seen. What could be wrong with her and what can I give a baby this small? She weighed 3/4 lb. at birth and weighs 2 lbs. now.
