A knock or doorbell can trigger excitement, anxiety or a fast dash to the entrance. Door safety is easier to learn as a predictable routine than as a frightening warning about strangers. The rule can apply to every visitor—including people the child recognises—so the child does not have to judge who “looks safe.”
The National Center for Missing & Exploited Children’s KidSmartz “Check First” guidance teaches children to check with a parent or guardian before going somewhere, helping someone or accepting something. At the front door, families can adapt that idea into three concrete steps: check, ask, wait.
Teach check–ask–wait
Check: hear the bell or knock and stop at a marked waiting place away from the door. Ask: tell a trusted adult, “Someone is at the door.” Wait: keep the door closed until that adult says what happens next. The child does not need to answer questions through the door.
Make the environment support the rule
Use an age-appropriate lock placed out of reach of younger children, a door chime and a clear waiting spot. Adults should model checking a peephole, window or door camera without opening immediately. Safety equipment is a backup, not a substitute for supervision.
Practise different familiar scenarios
Role-play a delivery, neighbour, relative and maintenance worker. Keep the same response each time: the child alerts a trusted adult and waits. Include what to do if no trusted adult answers: move away from the door, do not unlock it, and use the family’s agreed help plan. Never ask a child to keep the visit secret.
For older children, discuss that uniforms and familiarity do not replace checking first. Praise following the routine, not guessing a visitor’s intentions. AutDHD’s guides to home-alone readiness and help-seeking can extend the plan.
