I got to thinking, after I asked you about knowing the Hermit Crab book, that I may have a little book list for you guys.
This, obviously isn't an inclusive list, but just some off the top of my head books that I have found to be both fun and wise:
Oh, The Places You'll Go by Dr Seuss (what list would be complete without a Dr Seuss???)
Scaredy Squirrel by Melanie Watt (there's a whole Scaredy Squirrel series!!!!)
Baby Honu Saves The Day by Tammy Yee
and, just for the pure fun of it: Don't Let the Pigeon Drive The Bus by Mo Willems (and there's a bunch of Pigeon books too, which is super fun- there's even a little cute chick in one)
