He needs to ask mum n dad if he can play before taking the toy! And if play, can only for a limited time… I tell him because he needs to rest his eyes!! After sometime he will listen n always ask first~
Have u tried to play "actual" games with your b? like board game and family games, if they find it more fun they will not think about playing computer first, but ask u or friends/family members to play with them~ u can buy travel pack games which u keep in ur bag!!!
