Make the arrival plan concrete
Explain who is coming and what the family expects to do together. If the child will join a meal but can return to their own activity later, say that. If they are expected to help greet or set up, name the small task. Avoid a vague instruction to be sociable that leaves them guessing how long they must participate. The screen decision should fit the actual visit rather than stand in for every expectation about hosting.
Choose the stopping point early
Ask whether the current activity can save or pause and agree on the action to take when the reminder comes. If a new match or episode is too long for the window, choose a shorter alternative. Give notice before the door opens when possible. If guests are late, explain whether you are extending the session or keeping the original stopping point. Do not let uncertainty become a repeated cycle of starting another activity and then urgently interrupting it.
Keep the handoff welcoming
Help the child save their place and move into the agreed part of the visit. If they need a moment before joining, accommodate that where practical without describing them to guests as the person who would not stop watching. Afterward, review any recurring timing problem privately. You can adjust the next visit’s plan without turning one awkward transition into a judgment about the child’s manners or interests. A clear expectation and a usable stopping action often matter more than a longer warning.
