Air out
Opening the window feels harmless to an adult. For a child who just settled into the room, it's a sudden sensory flip, cold, breezy, and suddenly the traffic is audible. The visual support below gives the warning that words alone don't carry.

About this visual support
Airing out is one of those small actions that looks like nothing but can unsettle an entire afternoon. The room your child just settled into suddenly changes temperature, the wind moves papers around, and the street's soundscape pushes in. For someone working hard to hold a stable sensory environment, that's not a small thing.
Visual support for airing out works mostly as a warning. The image shows that the window opens, how long it stays open, and that it closes again afterwards. With the picture seen ahead of time, the cold air has a beginning and an end instead of just being a sudden scrape.
One concrete tip: tie airing out to a short, fixed moment, for example while teeth are being brushed or someone is in the bathroom. The sensory shift then happens while your child is already moving, not in the middle of an activity that took focus to start.
In the Routined app, airing out can sit as a recurring small step inside a household routine, so it ties into other moments instead of arriving as a surprise.
