A.C.
The Berenstain Bears Learn About Strangers was a really good book. I bought it for a friend's son, and I've seen it at the library too. It was really, really good and explained it better than I would have thought to. Sister Bear gets a little sad, too, and the world seems scary for a minute when she hears she's not supposed to talk to strangers, but her mother makes it all better and explains it really well for very young children with apples. I thought it was great because I don't want my son to lose his innocence and childish happiness, but I want him to understand "the rules" and why, in a way that is fine for a toddler.
