When we go out and it is busy my son will come home and shut down.
He needs time to chill out and wind down.
He takes himself off somewhere with his blanket and usually his ipad and some milk and just shuts down to the rest of the world.
He has done this today, this morning was extremely busy, we did 3 separate activities in a very short amount of time, swimming lessons, then library and then soft play, we stopped at the shop and bought sausage rolls and pastries for lunch on the way back and by the time we got home he was ready to zone out.
He will probably need at least half an hour after such a busy morning but after that he will be fine again, its unlikely that we will be able to go out anymore today, but if I am honest I am not sure that I would want to anyway.
