my son had fever. today he didnt have fever and is ok. bur he stopped eating rice. rice us our staple food. till now he doesn't eat anything except rice. he doesn't like biscuits or anything. but this time post fever he just don't want to see rice. I thought he is having mouth ulcers but when I tried feeding noodles and he had nicely. In fact he had bun as well which he never use to eat. it's been since yesterday he didn't eat rice. what to do?
