Hi, my daughter is 3 years 9months old. She has recently started going to school. She is developing a habit to touch heself / stimulate herself with her hands or using an object like the edge of a table / bench. we noticed at home and tried to council her. the same issue has been noticed by her school. I have tried talking and explaining to her. she stops it for some days and resumes again at school. Could you please help me understand how to explain her not to do this, esp in public places. please guide me on this.
