Overall, it was a great book and represented the importance of stranger safety and safety in general very appropriately. It was also engaging through a story of a little girl meeting her new baby brother.
A book about "stranger saftey". I would read and review this book every year during the first days of school, and review it again periodically through the year. The messege of this book is important and something children should memorize and practice.
This seems pretty good for what it is. Hard to write a book that won't totally make a kid be scared of the world. Not ready for it, but maybe try again in a year (age 6).
