i tap my son's hand to make him understand that he he shouldnt put his hand on certain things... problem is he likes it and find it funny so it has the oposate effect.. he keeps putting his hands on stuff he shouldnt waiting for my to tap his hand😐 i talk to him in a big loud voice (not yelling just louder) and i make the angry face, i touch it and i pretend to cry like it hurts... and its just a big funny game for him.. i know he is still young but i dont wanna let him hurt himself just so he learns... if he does.... what can i do? he started unplugging stuff, removing batteries from controllers, and chewing on cable...
