Teach your kids about “stranger danger”
While it’s important to teach your children courtesy and politeness, they should also know that they should never, ever speak to strangers when they are alone. Teach this in a non-alarmist way – you don’t need to scare them into submission, just establish basic rules and follow them yourself. (Lead by example.) For example, tell your children that they should never open the door to strangers and should always ask a visitor to identify him or herself. Whenever the doorbell rings, make sure to get a verbal ID before opening the door. If you make something regular practice, your kids will, too.
