Feeding issue? : Some children are cow's milk intolerant, because of course if you were meant to drink cow's milk you'd be born a cow. Gassiness, bloating, and stool changes are possible. Allergy to milk is also possible though less likely. Reflux is also less likely. Discuss this with your peds at your next well check, and see what issue needs to be addressed.
