DD aged 5, almost 6, DS aged 2.5 and I have been 'tidying' our bedroom and a spare area near out loft room, which has been full of confiscated toys. We went through, gave some to hospital, threw some away and kept some. DD took some of her toy that she got back and went to the now clean space next to the loft room (a 'cupboard' that has not yet got doors on it). DS followed her and she stared him out, right in his face 'do not come here, this is not for boys' and I told it was an area they could both play in, she said she wanted to play alone so I said she should go to her room to play if she did not want to play with him (she is allowed to ask him not to come in there if she wants time alone).
Anyway, he went there too and was playing with his own toys. They argued, as often then do, it seems he might have hit her with a toy but i did not see. I turned to see what they had argued about and I saw her consider, then take a swing at him, in the stomach, hard it was calculated and she had a very mean face.
Immediately I told her I saw that. She did not initially attempt to make an excuse but looked like a girl caught hitting her brother hard.
I was so angry. He is little and she can hit so much harder than him. I know its difficult for her when he gets cross with her and behaves badly, but he is only 2.5. I have told her countless times not to hit him back but to tell me and I will tell him off. He is not able to lie at the moment so I ask him if he hit DD and he says yes and then I put him on The Step. I try really hard to let her see that when he is behaving badly I address it, but make it clear that she must not hit him but talk to me.
So, my first reaction was to shout out some random highly unrealistic punishment, but realised this was going to shoot me in the foot if I made it inpossible to achieve, could not think of anything serious enough (she is already not allowed the computer for bad behaviour today) and I want to consider it properly.
So I have sent her to her bedroom for 10 mins while I calm down and so does she. I have told her not to play, speak to me or DS and that I am very cross and sad.
How would you address it? DS is over it already and she is becoming restless already.
