she's just horrible...every morning she literally growls at me, snarls, is rude to her sister, moans about her breakfast.
Every day I collect from school & she growls at me, barks, what have you got me to eat. She barely speaks to me. WHen I pick up DD2 from nursery she is all smiles, kisses & cuddles.
At the weekend she is bossy, is rude to me (in particular - DH tends to let it go), stroppy, one of her favorite sports is antagonising her sister (age 4).
We went out yesterday, yes a boring shopping trip. It would have been much quicker if DD was able to wait patiently whilst we looked at stuff. But no, she had to fuss, disappear, touch stuff.
We had her parents evening the other day, apparently she is a lovely girl. Which she can be, but her & I are just at loggerheads 
The thing that gets me, is she is so angry. But I can't see what there is...other than she seems intensly jealous of her sister (small, cute, happy, east going. I've asked her about this & she says she wants to be small & cute. Yet all DD2's little friends adore DD1.
I feel like there is some connection going wrong in her brain..the trouble is, she is ruining home life. she has always been like it, she came out of me angry - little red angry face with fists. (DD2 barely opened her eyes when she was born), I am wondering if that is something to do with it. She doesn't walk, she bounces & skips..so much energy (she does several physical activities after school)
Anyway, she has been warned & warned over her behaviour this morning. DH was taking them to the park, but she was moaning about coat/jumper, telling DD2 she was ugly, making her cry, all whilst checking her hair is ok. She had a warning, they go outside then next thing DH has plonked her back in the house & is tkaing DD2 out for a bike ride. I'm in the lounge ironing & see water being poured out off the window. I've then gone up there, been very angry, screaming & shouting at her (completely the wrong thing to do).
I feel like i don't want her anymore (which is terrible & I'm not going to harm her) but I'm just telling this because i really am at my wits end. I feel at the point of either she goes or I do. This has been going on for a few week. I understand there is talk of tiredness etc (she's yr3) BUT it's not accpetable. She took something from the inlaws last week & lied about it. I asked DH to find out what was going on, but she said no, but then (when I insisted he push on hte q's) she said she had. She took it because she wanted it.
I'm worried- I'm worried that I can't control her or get through to her (make a connection etc) at this age, with myself shouting & being angry & what on earth is going to be doing in a few years time ? And she's destroying our family. She is so demanding - is she ill ? how can this be normal ?
Please help...
