Any advice would be gratefully received. I have 2 girls, Ellie is 6 & Izzie is 4. Ellie is a very good girl overall but Izzie is the complete opposite. She doesn't care when she loses treats as a punishment, when we tell her off she is very angry and always shouts or hits out in frustration. She also laughs when we tell her off, there is never any remorse. I always follow through with what I say & am at the point where I don't know where to go from here. Any ideas?!?!?
