#AskTheExpert. my son has his first summer in india. he always asks for water. I have to reduce his meals cz of his over drinking which ends up in vomit. after 3-4 hrs he eats something but within the gap of two meals he keeps drinking water. he doesn't want to eat even though he's hungry. should I get worried abt his habit of vomit? people r saying this will make his stomach weak. my son is active n poops well daily. please suggest.he's three years old. we have permanently shifted to India.
