A few weeks ago, I reported about Yoni Ploni Never Talks to Strangers, a book written about personal safety specifically for children in the Jewish community. (See the original post here.) This book is now available through the Israel Book Shop website.
Another book on this topic has just been released: Artscroll's Let's Stay Safe. This book had a wider subject area than Yoni Ploni..., as it covers such topics as crossing the street, bicycle safety, etc. as well as stranger safety. You can find Let's Stay Safe at Jewish bookstores and online on the Artscroll website.
