DSD (12) has long been bullied by DSS (16). DH has tried to come down hard on DSS but he just holed up in his room and waits to go back to his mothers. DSD has endured years of being called fat, ugly and being physically pushed around. He will sit on her when she's on the sofa and then when she struggles to get out from under him start hitting her. He is constantly in her space trying to trip her or pushing her. He happily told us he had "silenced" her and that she knows better than to ask for help now.
She's the most laid back kid I've ever met. She has never retaliated until this year. Apparently he was emptying his bin from his room at his mums and he dumped it over her head and then starting slamming on the sides of it. She saw red and got a knife from the kitchen. Her mum managed to intervene. Their mum told us none of this. According to them this is all because DSD has started her period and is hormonal. It's utterly ridiculous. I feel so bad for DSD. We have offered for her to live with us but she won't leave her mum/change school. I really just don't know how to help her. It's been 8 years of this going on. I'm really starting to hate DSS and don't even want him around. I just don't know how best to support DSD.
