Welcome to FitDay. Maybe your husbands skepticism will be enough to motivate you to prove him wrong.
I have a friend that has a son with Autism and I recently did some training on helping families with special needs family members. While I can't relate b/c I've never lived a day in your shoes, I can imagine how hectic a day in your shoes can be.
Good luck with everything and if you have any questions just ask.
ON EDIT: I almost forgot to ask, are you related to Harry Connick?
