Ever since ds2 was born 6 months ago we've been on and on at ds1 (3yrs) to be gentle with him yet every single day he is too rough or hurts him on purpose at least twice. It breaks my heart it really does. I can't leave them alone ever without something happening. I recently caught ds1 putting a pillow over ds2's
head. I'm terrified he will one day seriously hurt his brother. I feel panicky and depressed about it. We've tried everything from shouting to giving more positive attention to punishments and even the odd smack when my mummy lion instincts have got the better of me :( but nothing seems to stop his horrible behaviour. Any ideas?
