Safety is--for obvious reasons--a high priority in our community right now. A friend recommended the book described in the link above. The article suggests that it introduces strategies to children so they can avoid being harmed by adults around them, yet approaches the subject in a way that is appropriate in our community.
In the comments section of the article, it makes clear that this book focuses on interactions with malicious strangers. Statistically, most children who are harmed (lo aleinu) are harmed by people they know. The next printing of the book will have this topic added.
The book has endorsements that have led me to place the link here, but I have not read the book myself yet. If you have and have any feedback to share, please feel free to add a comment below.
