It is better to observe secretly and solve it as soon as possible. Many children are stressed because their parents go to the teacher to learn about the situation and are laughed at by their classmates.

Finally, there is a way. I have to pretend to be very leisurely when I go back every day these days, and spend money to let my children go out for a walk.
