My daughter is 7 turning 8 in April, she doesn't listen, mostly ignores. When you tell her to do something she doesn't do and says she forgot(2 secs later?) She lies, she blames her brothers as the reason for not doing something, she can do something right in front of you and say she didn't. Sometimes she will lie and when I ask her about says she didn't tell me that and then I tell yes this is what you said to me she say "I did?" like she did it with out knowing. She doesn't care about hygiene and frequently "forgets" to shower herself. . I can't deal with it anymore and think I am harming her more by getting upset and yelling at her. I was so ANGRY with her last night i raised my fist but i NEVER! used it i had the urge to cause she made me sooooo angry .... All we ask of her is to clean her room clean up the mess she makes in the kitchen help with the setting the table ... plates and cutlery and the help with the dishes..... Are we asking too much for a nearly 8 year old i also have a nearly 6 year old boy who has to clean the lounge of his toys and clothes he has left lying around, help with the dishes as wel,l might be putting them away or helping with drying them , our 2 year is only a baby but he has to clean up his room and he tries to make his bed (i will go in after i have dropped him at daycare and go and make it) Is there some sort of therapy she could use? PLEASE HELP!!!

Have use lots of different types of disapline
Ranging from taking the computer away from her
to smacking her
to taking treats from her
to giving her cuddles and praising her when she has done something we agree on
removing privilliges away from her
keeping her up 1 hour past her bed time to make her finish the job (she has got into her head if i go slowly mum or dad will tell me to go away and she get out of it) usually the dishes we get her to wash them if she has mucked around and we have got one of the boys to get the plates anf the other to get cutlery
Have tried ignoring her till the job is done
Putting a cup of water in the microwave set on low and giving her say 10 minutes to have completed at least one job or have made an improvement

I NEEED HELP can some one help me out with the problem
