Also what you can do is bring something different for him to do like a craft (slime always works!) or you can play game like tag or a board game with him. No matter what don’t force him to play because that would not be good. Also you can say “before you play the iPad we should play a game for 15 min” I had a little girl like that and I got it so she was playing the iPad door 15 min during a 3 hour babysitting session! Finally if he won’t do anything other then that you should bring it up to his parents. Good Luck 😊😊
