he is 2.2 years old. this has become a problem in the last week or so, though in truth he's hit smaller children before, much to my shame .
I have tried gripping him firmly and telling him off in a firm, cross voice, but it seems to have no affect at all. the minute i loosen my grasp he swings for me again. we have tried the 'naughty step' but he quite likes being on it . the only other thing we do is put him in his cot and shut the door. but nowadays he can climb out of his cot so he just ends up playing with his toys with a "do i look bovvered?" expression on his face. please help!
