i'm really struggling with my 10 year old. his behaviour is very challenging. He is constantly winding up his sister, this is every day to the point she is screaming and crying every day. I discipline him but it doesn't change. this is not through lack of attention (it's been mentioned to me he may be doing it for attention) he isn't, he gets attention without her, he helps me cook, bake, build things, we play board games just us, i even play roblox occasionally with him. so not to do with not getting attention, he just doesn't get me to himself but none of them do that's one of the downsides of being a lone parent. The teasing and winding her up is becoming too much for me. like yesterday i was trying to clean and all he was doing in the other room was teasing her so every 5 minutes i had to stop what i was doing to tell him to stop. this was causing me unnecessary stress, and sometimes i end up shouting because he doesn't listen when told repeatedly not to do it. how do i explain to him that he is making my life harder and more difficult? i am a lone parent so i don't get time away from him like other mums do with their kids so maybe they can cope with it more because there are breaks to look forward to but i am with him every day other than when he is at school so it's constant stress every day. How do i get him to understand that he is causing me stress every day? and that i am parenting him alone and he needs to stop trying to make my life harder? my other kids are fine when he is not around there is zero arguments or fighting
