I hope by now your child is over the flu, but just some advice if not, or for the future. My son had a horrible stomach flu about 2 months ago. We made the mistake of trying to give him milk and his regular food too soon. Our doctor told us that they do not respond the way adults do because their digestive tracts are so immature. Therefore...she told us to only give very bland foods: rice cereal or oatmeal mixed with water, bananas, applesauce, crackers or cherrios for about a week. That is about it! The most important thing is keeping them hydrated. So lots of water, but in small amounts at a time. No milk though. We had to keep our son off milk for one week. Our doctor told us to introduce it back slowly, i.e. 1/4 milk, 3/4 water for a whole day. Then if they can stomach that, then 1/2 milk, 1/2 water the next day, and so on. Pedialyte is best for while they are sick, but it doesn't taste the best. My son wouldn't touch it so we just stuck with water. Hope that helps!
