What's your fave kid's book?

[astrldec]

I thought it'd be fun to see what everyone's fave kid's book is/was! little_ole_me had a post about Snuggle Puppy and it made me think about all those adorable kids books that you can get.

So, please, share!

What kid's books have you read and loved and will most DEFINITELY own when you have children of your own???
