My one year old consistently has a loose yellow stool. 2times a day, occasionally 3. This has been going on about 2 or 3 months, hes very healthy, not losing weight, seems fine. Hes always very congested and has wheezing, maybe the weather or pollen. Foods are the same pretty much except he has been drinking whole milk. He always begs for my bottles of water, could thay be a sign of dehydration? it could be the milk, but wouldn t he be in pain or some discomfort? What is the best milk substitute to try for a few weeks. Or other suggestions. Thank you.
