My 3.5 yr old son got up at 3 and vomited some rice and chicken he had at night. He then vomited water just after I cleaned him. Now again he woke up at 8:30 and vomited water twice. Anything I can give him. All this while his tummy was aching. I put asafoetida powder in warm water around his naval and stomach ache stopped but not feeling too well.
