Safety Tats are temporary tattoos that you add your cel phone number to – and they seem like a smart idea.
I worry a little that they could make parents a little less vigilant, and I want to emphasize here that teaching your child to stay close and to know how to handle themselves if they become separated, or are approached by someone they don’t know, is most important (see this post). But these temporary tattoos mimic the arm band programs offered at some amusement parks, and could obviously be helpful in some circumstances.
