My ADHD kiddo thoroughly enjoyed this book. He struggles with the concept of time and I think the methodical explanation helped him understand which he appreciated.
This is a great book to teach the concepts of time passing. It starts very small and moves to very large using simple things that a child could understand. This is probably pre-K through 2nd or 3rd level. Not one I would read for a storytime. More one that is good for children who are learning or interested in time. I may still book talk this one so that I have plenty of books at the storytime! :-)
