I asked my HV about this but she didn't seem concerned, so i'm guessing i shouldn't be either but it's still bothering me. My DS used have a BM once a day, and it would be thick and pasty (he is Bottlefed) then when he turned around 11ish weeks(now 17 weeks) his stools have become runny(although i would not say diarrhea)and containing mucus. Could it be related to teething, which i am almost definatly sure he is, or should i take him to the GP because its been going on so long incase it is something more sinister? Has anyone else experienced this?
