While picking up a Woodman's Pal a few months ago, I was perusing their site, and came across a book that they offer. It's called "How to Lost-Proof Your Child".
Anyway, I just got to reading it yesterday, after getting home from an awesome 10 days in Acadia National Park with my wife and kid, and got to thinking about how little I was prepared for my kid getting lost.
The book is a quick read, and seems to have a lot of good info; simple stuff that both you and your kid can do. I have already started going over with my almost 5 yr old daughter, and plan on carrying it thru.
Just wanted to pass the title on. I have no stake in the book or the seller, but as a parent, this seems like pretty good info...
