Five Funny Critters  are probably the most complete hypnotic program released for children, narrated by John Dyckman Ph.D.

Overcoming fears and reluctance, learning new things, becoming even more optimistinc, sleeping naturally and interacting with other people with self-confidence are some of the areas the program touches. 

I haven't yet had the opportunity to review it myself, except listening to the sample session available at the above link.
