My 19 month old son has been hitting out at other children and me for a few months, I thought this would go away by itself, it had seemed to have improved but has now made a come back. He seems to hit for attention, when things aren't going his way and sometimes for no real reason or trigger. I don't want the other children that we see regularly to be scared of him and would love any advice of what to do!! Its really upsetting and not how I thought my little boy would be. We don't smack and he gets lots of attention, stimulation and activity. Thanks.
