Once we mockup our UI, would it be possible to have you give feedback / provide suggestions? Could you help us put together a user-trial with say 10-15 tech-savvy parents like you?
You can contact me via the email address on any of the websites in my profile. I belong to some health lists. I would want to ask the list-owners permission first, but I might be able to help you put together a trial. We can discuss more details via email.
