I discovered The Very Hungry Caterpillar by Eric Carle when my now 7 year old granddaughter was a baby. What I found was a stuffed caterpillar with a jingle bell inside. She absolutely loved it and wanted it all the time. It went to town and to bed with her. Later I found the book for toddlers in a board book. I think we now own about 3 of the same book but in different forms.
I have found that there are so many developmental toys, games, and figurines, snow globes, cards, and other things that go with the book that I have been amazed. Of course, he has written several other books that the children love too. So, I was delighted when I found out that Totsy was having a sale on these books, and other items. Take a look and see if you can find something you like. They are up to 50% off right now. There are also the books he has written with Bill Martin Jr., like Brown Bear, Brown Bear, What do You See?
Of course, Totsy always has lots of good bargains on children's clothes, toys, shoes and things for mom too. One of my favorite websites.
