I am at a loss as to what to do. She is having a meltdown 1-3 x a day. Her behaviour is very controlling towards us - e.g. some of this is over food, wanting her sandwich a certain way or just the right amount of cereal in her breakfast.
Tonight, I was at my mum's til 8.45. She wanted to go home and when we got in, she refused to clean her teeth, saying I had to do it because she was tired. I refused as I'd done a day's work and was exhausted and, at 12, frankly, we're past this stage. The upshot is she gets increasingly angry and insistent and pours her entire water bottle over her room and her bedding (so has the energy for that). Her argument is I kept her at my mum's too long. Her younger brother, aged 7, didn't mind and just got on with it and it's not as if we have to get up early.
If I issue a consequence, it's like pouring water over a fire. When calm, she concedes her behaviour is unreasonable but there is nothing I can do to either prevent it or stop it from happening again.
Of course, if we give in, then, yes, we can stop it to a point but then she'll make the requests increasingly unreasonable - almost to see what we will say or do.
Her brother is not perfect but, normally, if we try to discipline him, he'll respond, maybe not first time but definitely if we are firm and consistent. With our daughter, it would not matter how long we tried, the outcome would be the same. This has been the case from day 1 - even with sleep training, toddler taming, toilet training etc, etc.
I am very anxious about where this is going and how much longer I can put up with this. I don't enjoy parenting and don't have the strength of character for this.
We have been to the GP over her food anxieties - e.g. worrying about throwing up if she eats too much - but they're not concerned yet as her weight is OK for now.
She has had support at school for issues with concentration and poor academic performance and they have been amazing but now she is having trouble with friends actively leaving her out of things and planning stuff in front of her.
