♀? Correct posture
Always remind yourself of the correct sitting and standing posture, and consciously correct your sitting (standing) posture during quiet activities, and children will naturally imitate it.
♀? Walk more.
Walk back and forth more when you are active, and touch their heads or small hands with your hands as a hint.
Chat with children
Consider children's age and personality characteristics, chat with them often, pay attention to their movements, and the teacher will take the initiative to stop them when necessary, or simply ask them to be like teachers, okay?
