Children over two years old generally don't go to kindergarten now. They usually wake up naturally. The best time for breakfast should be around 8: 30. Generally, it is more appropriate to drink some water after getting up, and it is more appropriate to give children breakfast after 20 minutes or half an hour of exercise. Therefore, it is more scientific to follow the time when children get up. Generally speaking, I think it is more appropriate to have breakfast around 8: 30, which will not affect the children's lunch.
