Looking for advice here. I have 2 dcs - DS(8) and DD(6). Ever since DD was born, DS has not liked her and done some very nasty things to her. I assume he is very jealous. When she started to crawl he would pull her feet so she couldn't move, and hold her ankles when she tried to walk.
This has got worse and worse over the years, to the point where he now will not even sit next to her or touch something she has just touched, and he will start shrieking if she looks at him. He still does all the nasty things too - today he deliberately tried to make her fall off a swing. Luckily she managed to hold on. He does these things with a look of delight on his face. I think he really wants to hurt her.
I am so worn down by all of this and feel I can't leave them alone together for fear of what DS might do. I realise this sounds like the Horrid Henry/Perfect Peter scenario, but honestly, DD does not provoke him or intentionally annoy him. I sense she is starting to figure out that if she cries then DS might get into trouble, so I try to ignore her if I think that is happening. But usually I have seen him do something.
I have been trying to ignore small fights and leave them, but now I feel this has gone too far and I wonder if a zero tolerance approach is needed? When he tried to make her fall off the swing, I told him he would not be getting one of the muffins I baked after school, but DD would, because he was so mean to her. Last week I cancelled a playdate because he went into her room and deliberately smashed up the lego she was building. I asked him why he did that and he said he was walking past and just thought how horrible she was so he did it. He has never apologised, for anything.
Would really appreciate advice. Thanks.
