If they get lost or bothered, teach them to go to a cashier for help. Don't place your child's name, first or last, on clothing, hats, bikes, wagons, etc. Remember, a child responds to a first name and a stranger using that name will automatically not be thought of as a stranger. Teach your child to avoid strangers. Teach them that strangers are people they don't know very well.
Strangers are nice and mean, pretty and ugly, rich and poor.
Be involved in your child's activities. Know your child's friends. Practice with your child the ways that he or she may walk to and from school or a friend's home. Make it clear to your child whose home he or she can go to visit or play. Notice if someone pays any undue attention to your child.
