What you are seeing is flow — the state where your child feels their best and is fully engaged. Your child is finally moving, playing outside, or deeply engaged in physical or social play, and the required activity is waiting. Movement and active play are not extras at this age. They are the primary vehicle for physical development, social learning, emotional regulation, and cognitive rest. A child who has been moving freely and then transitions to a seated task will actually perform better on that task than one who was forced inside before they were ready. The goal is a transition that honors what was happening.
You are having so much fun. We need to do our other thing soon. Let's find a stopping spot.
