We really enjoy "But not the Hippopotamus" and "The Going to Bed Book". If you don't like those, I think you're probably not going to enjoy others.

For younger kids, Blue Hat, Green Hat, and it's quite adorable when little kids complete the "Three singing pigs say..." "La la la!" (Moo, Baa, Lalala).

My younger kids had several Boynton books memorized, and I agree with the grandparent - I enjoyed the interaction with the children while reading them.

Moo Bah La La La is a favorite. I also like The Going to Bed Book.

My kids love the Belly Button Book and I do, too.
