What to give a child for upset stomach and vomiting?

Oh, that's so worrying! For upset stomach and vomiting, definitely focus on hydration with ORS, given very slowly. I'd be so anxious about them getting dehydrated. After a few hours without vomiting, maybe very bland things like plain rice or a tiny bit of curd. But seriously, if it continues, a doctor visit is a must!

I've heard ORS is always the first thing, right? And maybe no milk or heavy food. But for how long after the vomiting stops should they stick to only plain things? Is homemade lemon water also good for hydration?

My kids have gone through this many times. Keep ORS ready at home. Give a spoon every 5-10 minutes. If they can hold that down for a few hours, then you can try little bits of plain khichdi or plain idli. No milk, no juice, nothing acidic for at least 24 hours. And watch for dehydration signs.

ORS is a lifesaver here, and thankfully, it's quite inexpensive. You can get a packet for a few rupees. Having it handy saves you a costly emergency visit later for dehydration. For food, plain home-cooked rice and dal are the cheapest and safest options after they recover a bit.
