Tab - when I have had fosters who eat too fast and throw up, I split each meal into 3 portions, giving them a 10 min break in between - that way they still eat the right amount before I go to work, but enough time so they aren't sick. With Finn, I had to put the bowl on the bookcase so it was that bit higher, that worked as well as splitting his food up. I do the same at tea times too.
