My nephew in the fourth grade of primary school is so naughty that his hands and feet keep moving. How to educate and guide him?

It is normal. Naughty children should be guided normally. Children have a soft spot for cartoons. In front of comics, other things are not very attractive. Adults often say that they are as happy as children getting new toys. This is a child's nature, but ADHD should be considered. Children are prone to zinc deficiency, so they should be conditioned in time and pay more attention to their diet! Don't restrict him too much.
