I have a little guy who was going through the same thing recently. I finally was able to convince the parents that it wasn't normal and they decided to try him on a lactose free diet...it was cured instantly! We don't know if he had gas pain as he doesn't talk, but he definitely had frequent loose BM's and they caused diaper rash just due to the frequency. Now he's down to one normal BM per day and no more rashes...phew! However, I would suggest having him taken to a doctor as it could be other foods that he is intolerent to. If it were raisins or grapes, you usually see them in the poop...my daughter used to have problems digesting them and they would come out almost whole. I never serve raisins unless they are cooked because I find they are not easily digested by little ones.
