I have two DSD (11 and 5) who I've always, up until recently, had a good relationship with. However, over the last 6 months or so, the older SDs behaviour has really deteriorated.
She physically and emotionally bullies her little sister, to the point that leaving them alone together for just 5 minutes results in crying and injuries. She takes her stuff, hurts her and calls her names and just generally winds her up constantly to get a rise out of her. I'm worried for the little ones self-esteem, and honestly her physical safety as she's been pushed to the point of knocking her head a couple of times now.
Her attitude with me and my partner has gotten worse too - attitude and answering back, and personal insults directed towards me. Poking me and making daft noises with the purpose of being antagonising. Its getting difficult to do anything or go out as a family because as soon as she gets bored, she starts playing up and whining until we have to leave. Just majorly unpleasant to be around. If we have family or friends round, she misbehaves until the attention is back on her.
Any telling off (and she has had MAJOR telling offs) is met by smirking and snide comments, it doesn't seem to phase her at all.
I'm just at the end of my tether with her. She's almost as big as me so I'm concerned that if we don't tackle this now, it could result in physical violence directed at myself as she gets older, or at least a loss of even more control over her behaviour.
We've tried giving her more attention, "killing her with kindness" including one-on-one attention with both me and my partner. She comes for an extra night in the week now and we take her to her club. She's not lacking attention, or comfort, or anything she needs. She has her own bedroom with everything she could possibly want. Her grandparents and aunties etc also struggle with her behaviour.
I want to support my partner in this but I'm just at the point where I want to back off completely. She says typical pre-teen comments like "I don't need looking after" and "I'm not a child" and this weeks favourite "you're basically just like a neighbour". I found this really hurtful when I do so much for her, doing her laundry, cooking meals, buying her presents, taking her places. I'm just tempted to stop all of it now. Other times (although increasingly rare) she's well mannered and thoughtful and quite needy with me.
We've tried the heart to heart talks to find out what's wrong or if she's reacting to something - she normally says she's just bored. But we giver her time and attention and things to do, we keep her busy. But we both have full time jobs and can't be on-demand entertainment all the time.
I'm not sure where to go from here. I want to support her but its becoming at the expense of my own mental health. She actually drove me to tears at the weekend.
Just hoping for some advice of anyone who's been in a similar situation, or has a child of a similar age. I know its a difficult age and she's been through a lot but this seems bigger than typical 11yo behaviour.
Sorry this was longer than expected!
