hi thanks for Query, I can understand it is difficult to manage children during the teenage, it might be due to their hormonal changes, exposure to new things and others , their reaction to that situation. there are many reasons for children's different behaviour, includes their expectation, peer pressure, age life style and others. You can approach with patience, calm and friendly manner, understand her emotions, rather than imposing your thoughts to her. you can take the help of psychologist to handle self and also your daughter. take care. stay positive.
