I've been taking mine for years, the older one hunts on his own now. things I have done:

- books and snacks, I use to read to them, now they read on their own, just make sure to train them to look around.

- game boys, sound off, do NOT use the head phones

When they are starting and young, do NOT push it when they don't want, bad weather, cold and boredom will take the drive out of a little kid.
