Don't really "turn off"
The traditional "isolation method" is actually to let children go to a boring place to calm down, rather than the real "confinement". Locking up will only make children feel isolated, and the "revenge" behavior after coming out may be more serious!
Emotional release
Why do they love to hit people so much? Because it grows too fast! There are too many emotions, anxiety and excitement in the small head, which can only be released through the small fist. Calm down, after all, you knew he would do it, so why get angry?
Live a regular life
Ensure that children live regularly, eat, sleep and play rhythmically. Irregular work and rest will make you grumpy!
Don't let them play alone.
If he always hits the same object, such as his brother always bullies his sister, then don't let them play alone! Seen from the side. Once you find your brother out of control, take him away quickly.
