Well, actually the concept of “stranger” can be confusing to children, so instead, teach them to recognize unsafe situations. Warn against adults who might stop to ask for directions or help in finding a lost pet. Tell your children never to go anywhere with an adult who doesn’t know the family password. Teach your children that it’s OK to run away or cause a loud scene if they feel someone might be dangerous. Talk to your kids and then role play to make sure they know what to do in an unsafe situation.
