Experts agree that a few simple rules can help to protect children from abduction: A child should never get in a car with a stranger, no matter what pretext or ploy he may use.
Use a password. A child should go with no one unless that person uses the password.
A child should never disclose that he is alone in the house if someone calls or comes to the door.
A child's name should never be in a visible place on his clothing.
Parents should keep a child with them in a store or public place.
Parents should never leave a child alone in a car, even for a few minutes.
