I think at the age of 7/8 your metric of success is tied strongly to how you control your body, probably due to all the reinforcement of this from years before.

I think at the age of 7/8 your metric of success is tied strongly to how you control your body, probably due to all the reinforcement of this from years before. At 12 things were likely easier for me. They use that ridiculous methodology now. For example my eldest's entire class was held back at the end of the day for 15 minutes due to one child's behaviour. Unfair and her ASD younger sister relies on her to get home and had a complete panic and breakdown over the routine change. Teachers surprisingly never available for comment after such things due to the layer of bureaucracy over everything. Formal complaint raised, pushed to the very end of their own self-inflicted process every time they screw up!
