R.H.
Children do this when they don't like what you gave them. The first time they throw up you flip out normally (save them) and they realize this causes them to not have to eat it. So they do it every time they don't like something. What you do is ignore it. I mean don't ignore the throw up but don't have a big response. Clean it up and go on. If you know it's going to happen plan for it. But never make a big deal of it. It will pass with time if you do. If you don't they will continue it and the list of unliked foods will grow.
