My daughter will be 11 next month, my husband and I are at the end of our tether with her behaviour. She flies off the handle at the slightest thing like asking if she needs to shower for example, and is always absolutely desperate for attention, she hates it when the attention isn’t on her and if my husband and I are trying to have a conversation it’s nearly impossible because she will interrupt or will stand behind me putting something on my head or waving the dog in my face. She is incredibly rude and says terrible terrible things in anger. She is unhealthily jealous of her younger brother who is 9 and for the most part very well behaved and always has been, despite this if anyone touched him at school she would fight to the death for him so she does love him. However she makes his life a misery by constantly trying to get him in trouble, and even trying to get attention from him when he is happily doing his own thing. She really believes we love him more than we love her and it breaks my heart. Everything is completely equal but she does get treated differently in terms of how we deal with her on a day to day basis simply because her terrible behaviour and verbal ranting etc cannot be ignored. She will also ruin things like Christmas Eve night and going to an escape room by constantly trying to take over and nit picking everything her brother does, it’s such a strain. My husband thinks we need to take her to a therapist, obviously this is hormones making things worse, but the hormones are exaggerating behaviour that has been there since her brother was born. We spoil her and her brother a lot, and I know we’ve gone wrong here, but I don’t know how to make my daughter a less entitled and more rational person. At school she is positively angelic and always being praised for her behaviour and kindness etc.
