In brief: Diarrhea/ rash
If present from birth, this often produces a chronic diarrhea with acidic stools that leave baby with a scorch looking diaper rash focused about the anus.
After a while yeast will often join & aggravate the rash.If the diarrhea clears after a week on lactose free formula, with a return after a return to lactose, your most likely lactose intolerant.
