My son is 12 years old, and seems to be addicted to mobile games. He started playing and using smartphone since april. We had to give him the device, to aid for the online classes, when wifi signals go, he can use his mobile data. But eventually, he started picking up the mobile game pubg with restrictions initially. Slowly he seems to be completely into it. He is very aggressive, who was a calm boy basically. Otherwise. Before it advances to a worse situation, please advise us how to keep him away from these games.
