My son, who turned 3 in July, refuses to try to do a lot of things. Refuses to try and pee on the potty, won’t try to pull his pants up or down, won’t try to put his own shoes on (he will take them off) won’t attempt to put his own jacket on...most of the time when we ask him to do these things he says he “can’t”. We ask him to try and if he truly can’t, we will help but he won’t even try. He will lay on the ground whining until we give in (because we need to leave or get him in bed, etc). He is insanely stubborn. We’ve tried bribing, telling him he’s such a big boy, telling him how proud we are when he does do things independently...I don’t know how else to encourage him to try to do things on his own. Any suggestions?
