OK, bottom line, my daughter loves this book. Loves the story and loves the pictures. So I have to give it an overall positive review because the primary purpose of a kid's book is to entertain the kids.
But I do have a little complaint, and I know how silly it will sound. This book is a follow-up to "If you Give a Mouse a Cookie" and others in the series, such as another of my daughter's favorites, "If you Give A Moose A Muffin." What is clever about these stories is that they develop a circular sequence of events that ultimately lead back to the beginning for what could be another in an infinite series of rotations through the steps. This book does not end so neatly. The mouse must return to the school to retrieve his lunchbox, hence you are taking a mouse to school again, but it is at the end of the school day, not the beginning. If there were one more page it would say, "Umm, then you'd go home."
I know, again I'm being too knit-picky for a kid's book. But parents will feel more enthusiastic to read a kids book where the gimmick is successfully carried out, not one that seems forced, as if the writer had a deadline. Or a nap to take.
Still, thumbs and tails up. I gave it four stars figuring I'd give five to Felicia Bond, the illustrator, and three to the author, Laura Numeroff.
