"Cade, for the next 20 minutes you can choose: Legos or go outside. Which one?"
Always: 2–3 options, a time limit, activities already set up and ready to go.
Never:
"Go find something to do."
⚠️
Movement first, always. Give 15–20 min of physical activity before any idle or quiet period. Skip this and the idle time will almost certainly fall apart.
