Lately my 5 week old has been fussing when nursing. He seems to have a lot more wind and he really struggles passing his poo's. I was thinking that it might be because he is now drinking a lot faster and therefore gets a wee bit sick and needs to get more wind up. The poo situation is really starting to concern me. He always seems to be in pain and is groaning even in his sleep. However, his poo's have always been the same i.e. soft and he farts them out. Is this normal??
