I don't know how to deal with her. She is wonderful at school; mostly A's, one B. Wonderful behavior except that she talks too much- not the worst thing she could do. But at home, it's different. She does great at her chores; she has 2 rms to clean and does them faster than her sister can clean one rm. She's a wonderful child in all that, but she is terrible in her attitude. I don't know if maybe I bring it out in her or what.
Her sister tells me she took her recorder. I ask her what she did with it. She says she doesn't have it. A search of her room finds it in her drawer and, of course, she says she didn't put it there. (She habitually lies, too, even if you see her do it, she'll say she didn't.) I tell her she needs to sit in time-out. She throws a fit. But mom, I swear I didn't do it. She's lying!! Stupid girl!!- to her sister, while she raises her fist and lunges at her. I tell her to go sit and she keeps on yelling, I didn't do it!! She's lying, I hate her, I hate you. I wish I was the only kid here. I'm going to kill you. This lasts for about 15 - 20 mins or until I've had it and she gets spanked. Her other sisters have been punished for stealing candy from the store or for knocking down a bush at the YMCA; they've been punished and had to make reparations; they may not like it but they never behave like this for any of it. She has to sit for 8 mins and she goes nuts!!
If anyone can offer suggestions about her attitude, temper control, or her lying, I would really appreciate it immensely.
