Establish clear rules: discuss and formulate rules about the use and study of mobile phones with children. If cell phones are not allowed to be used during study hours, then study hours should be uninterrupted.

Reasonable arrangement of study time: make a reasonable study plan for children to ensure that children have enough time to study.

Strengthen supervision: keep good supervision when children study and help them concentrate on their studies.

Praise and encouragement: when children abide by the rules, they should be given appropriate praise and encouragement to encourage them to continue to abide by the rules.

Participate in other activities: encourage children to participate in various interesting activities to enhance their interest. Through these steps, you can help your child to relax, concentrate on his studies and reduce the use of mobile phones. In this process, you need to continue to pay attention to children's emotions and needs to ensure that they get full care and support.
