Hi. Thanks for your query. Noted the history and understood your concerns. Since a 2 year old child is having recurrent problems of vomiting and loose motions in spite of consulting many Doctors and told about milk intolerance it will be prudent to have proper investigations to know the exact cause and thus get a proper management. I would advise you the following in such a condition: Get the stool tested for three consecutive days. Ultrasonography of the abdomen for lymph nodes, appendicitis, diverticulitis and any other problems. Tests of blood and urine. Clinical re-evaluation by another Pediatrician and if required by a Pediatric Surgeon. Once a proper diagnosis has been made a curative treatment can be done. In the meanwhile watch for the foods and beverages that instigate or enhance the problems and stop these altogether. Also watch for bloating, fever, local tenderness of the part of the abdomen when he has attacks of vomiting and loose stools.
