Hello.
My god it has taken ages to type this so apologise in advance for cross posts.
Been though very much the same thing with my 4.5 DD recently, and culminated in a couple of very shouty days which I hate, and doesnt work anyway with her.
I already had a sticker chart to help with procrastinating at bedtime when none of us are at our best but I didnt want to have to hand out stickers chart for every piece of the day where she was being a pain.
She also then floored me by saying, in response to me telling her if she didnt do X that she would lose Y (TV I think) 'I dont really care about that actually mummy'. (DH response was 'Well you've taken smacking off the table I have nothing to add..')
Anyway, I am wittering, in the end I sat down with sensible friend and talked it through and realised I just hadnt found the right incentive for good behaviour and I didnt have a standard response for bad.
I bought a huge job lot of Go-Gos on ebay (very motivating as older friend has them) and now have divided day into 4 sections. If she behaves she gets a tick , 6 ticks she gets a go-go, (extra ticks if she does something fab). Bascially if she is being good she can get a go-go every day and a half. If she ends up on the naughty step she gets a cross, another time on the step no TV, another time no tv no computer, a third time add no music. We havent ever got to a fourth time, I think my head would fall off with effort of not biting something.
To be honest at the moment when she starts being a pain she really seems to enjoy the confrontation and gets her na-ne-na-na face on and stomps dramatically up the stairs which pushes all my buttons for some reason. If I can hold it together blanking the low level stuff when she is spoiling for a fight and then just sending her to her room when she tries to pick a fight works much better than a lack of Tv etc- she REALLY hates being ignored, and it reduces my blood pressure.
So things are better here. She does seem to go in phases anyway, but I think the go-go thing helps us both focus on positive stuff and reminding myself how effective not rising to her is, has helped me simmer down.
My life however does now involve lots of moving furniture to retrieve odd little plastic men on as daily basis.. chose yee wisely your reward system for verily it may blocketh the hoover...
