At 6 weeks old I noticed my DS having blood in his nappy. It got worse until I took him to the hospital. They said he had a cows milk protein allergy. As I'm breast feeding him I need to cut out all dairy(I miss cheese and ice cream so badly!) . I've done this for nearly 2 weeks but he still has blood in his nappy. He also cries lots when I try to feed him. Anyone else had this happen? How long did it take for the bleeding to stop?
