When your vomiting, a lot of people think that they should drink a lot of water to replenish the body....BIG mistake! All you will do is vomit more. Drinking Gatoraid or something like it will stay down.
When your child is sick though, and you KNOW they need to throw up, give them a cup of water. It does the trick for my kids who will do every thing in their power not to throw up! PS be smarter than me and have that bucket ready! lol~ donna
