I Can Do It by Jana Novotny Hunter, illustrated by Lucy Richards.
When I picked up this book, I expected a toddler book about a small child wanting to do things by themselves: a subject that has been covered again and again in charming ways. But this is something different.
A little guinea pig boy is off to nursery school. His day is described in adjectives. One spread is about being FAST, another about QUIET, another about CLEVER. And the adjectives carry him through his day from entering preschool to being picked up at the end of the day. This is a great book for having conversations about what words describe your day and how you can change throughout your day. Add to that the fact that it is a reassuring, sweet book about preschool and this is a real gem.
