My two eldest DS’s are 4 and 2. Occasionally DS1 will pick on DS2 but for the most part DS2 is the instigator and it’s awful- he hits, bites and scratches his brother with no provocation at all. In the car he’ll be scratching at him, and because DS1 can’t move away this inevitably builds into them both screaming.
This evening on the way home from nursery he’d been scratching him in the car, and a few minutes after they got in he started hitting him on the back of the head with a toy for no reason at all.
He isn’t really talking yet beyond a few basic words- when he’s naughty like that we tell him off and sometimes put him on time out in the bedroom, and always explain afterwards what he was being told off for and why he shouldn’t do it, but it seems to have no effect at all.
We don’t know where he’s learnt this behaviour from or why he does it, or how to make him stop. Sometimes he can be so sweet it melts our hearts, and he’s absolutely lovely with his new baby brother- but such a little tyrant with DS1! What do we do?!
