DS1 is 3.2, DS2 is 10 months old - it seems that not a day will go by without DS1 hitting, pushing, smacking DS2
He did this from the day he was born which obviously we put down to his emotions at the baby arriving and made sure he was never in a position to be able to hurt DS2. It did stop for a while but seems to have started up again these last few weeks.
Most of the time he is fine with DS2 but, when he is bored, tired or angry with us for saying 'no' about something, he will head straight for DS2 and hurt him.
Me and DH disagree with how to handle it - I comfort DS2 and remove DS1 from the situation (another room, distract him etc) until he has calmed down whereas DH thinks he needs a smack To be fair to DH, he says my method isn't working either and he is right - it isn't making any difference to DS1's behaviour.
Any advice as to how we can stop DS1 hurting his brother - it is just awful and I have this horrible feeling that if it goes on much longer, it will ruin their relationship as DS2 will start to remember
