My ds is just coming up to six months and for the last three months has been having the most horrendous mucous filled nappies and sometimes traces of blood. The doc has now put him on horrible tasting hypoallerginic formula which he won't eat, even tho he was breast fed before. I still b feed him to get something down him. He has stopped talking, and he used to babble all the time. He seems to be alert and listening, and still smiles a lot, he just doesn't want to talk any more. Could this just be a phase he is going thru? Sorry for long message, just want to know about the talking thing.
