I can't imagine having to clean up throw up on a regular basis...that really sucks for you. I do have a daughter who is kinda picky, not too bad but when she doesn't like something she will just chew on it and keep it in her cheeks like a squirrel. She will keep it in so long that I have to force her to spit it out. She just can't swallow it if she doesn't like it. I don't think there is much we can do. I continue to serve healthy food in the hopes that with repeated exposure she will get over it. Which does work I think. But puking I would find very difficult to deal with.
