Difficult title really. Obviously all children react badly to punishment as it is never nice. what I mean is that punishment seems to make her behaviour worse. It makes her angry and stubborn and she becomes wilful and aggressive - verbally and physically. I'm not talking about her being smacked or anything, just stuff like not being able to read at bedtime, no screen time etc.
I praise and reward often (we have a pasta jar system running but she can take it or leave it) but she's down on herself and her self esteem is low.
