Here is the link to the HILLROM company <a target=new class=ftalternatingbarlinklarge href="http://www.thevest.com">www.thevest.com</a> Absolutely wonderful people. My husband is older and uses the vest, so I can't be much help with the child issue but is seems children would be more receptive to the vest than manual PT, they can still watch TV, attempt to read, color outside the lines (it's a little bouncey, Mark made me try it). It is also a great time saver, instead of me having to do 1 hour of manual chest PT EVERY am and pm for mark, he now does it on his own 20 minutes 2x a day.
Cindy, if your doc is still giving your gruff about the age, weight, height.... sicc the hilllrom company on them. Call or email, tell them you are interested and ask them to help you get it via your doctor, "please contact/send info to my childs CF doctor". They will do it in a heartbeat!
