My son's autism therapist recommended the Elephant and Piggie books. I don't remember which one she let us borrow but we've since bought this one and I've read it approximately 467,ooo times, give or take 3 or 4.

So Piggie and Elephant, aka Gerald, are best friends. This volume collects Today I Will Fly!; Watch Me Throw the Ball!; Can I Play Too?;Let's Go For a Drive!; and I Really Like Slop! All the stories are sweet little tales about friendship and my son eats this shit up, especially when I do voices for all the characters. My son's favorite is I Really Like Slop and we can both recite it from memory. Basically, Piggie whips up some slop, Gerald tries it and hates it but says he's glad he did because Piggie is his best friend.

Cute stuff. If my son's interest holds, I'll probably be reading and rereading volumes 2-5 several million times.
