How do I handle errors in a children’s application?

I'm developing a children's learning app for preschoolers where the basic idea is that the parent hands the device to the child, and is free to then leave the room. I anticipate, of course, that the app will run as expected; however, on the off-chance something does go wrong, it will most likely affect the child's ability to learn and progress. Thus, in such an event, I may need to notify the parent as soon as possible. Some ways I have thought of to accomplish this are: 1) Have my app say "Uh-oh" or some other sound over the speakers 2) Send the parent an e-mail using the address listed in the corresponding Address Book entry. In both cases, I would also show a message telling the parent what happened and how to fix it.
