I know this is OT but I was really hoping someone here could help me.
I have a 15m old who is having stomach trouble. He has gas and lots of tiny, soft stools then one big stool. When he is having the big stool he will cry for several hours until it comes out. He is crying like he is in pain.
I have been slowly introducing cow's milk and there didn't seem to be a problem. He was on formula from 6m plus and breast milk before that with no problems. He just recently switched to all cow's milk. It is possible that he could tolerate a small amount of milk but still have an allergy?
He also eats a lot of table food. Pretty much everything I eat except raw spinach.
His pediatrician can't see him until later this week. Does anyone have any ideas or thoughts that could help until then?

(He still has problems with constipation, mostly due to the fact that he attempts to avoid any and all veggies and fruit. Also I think he's just predisposed.)
