I dont remember as a child, but as an adult it happens. Its usually from more of a tickle in the throat type cough. I actually feel great afterwards. You get a bunch of crap out. Its the hard way to do it to. I would tend to agree with your docs...if the cough is getting better & overall she seems fine since she ate then I would just keep an eye on her. Emily is right about CF cough etc being quite different then other things. Once you learn to distinguish the difference it will be get easier. AND you will learn!
