What a great way to breach the subject of strangers with your little Disney fan! This book goes over all the safety rules, and why we shouldn't talk to strangers. As Christopher Robin explains these things to the lovable characters of the hundred acre wood, so too they are explained to your child(ren).
It's beautifully, and colorfully, illustrated by Tobbin Cuddy, and written by Kathleen W. Zoehfeld.
I read this to my children pretty often actually. It's a great fun theme, with characters they already love. And, it explains quite well that they shouldn't speak to strangers, and gives them safety rules that they should abide by.
It was only around $5, and it was one of the best purchases I believe I've ever made in the line of books for my children. I highly recommend it!
