My DD is 7 (nearly 8) and is incredibly defiant. I'm really struggling to deal with her. Tonight, for example, she decided right at bedtime that she wanted to wrap her teachers' Christmas presents. I said that we would do it in the morning as it was bedtime. She was very angry and went and came back with some wrapping paper and scissors. I again said no, we'd do it tomorrow and she then just started cutting up the wrapping paper so it was all jagged and too small for the present so wasting the paper. She only stopped when I raised my voice and took the presents away.
I get totally stuck on how to stop her when she's like this. I struggle with consequences for example, as my parents only used smacking as their response to everything which I obviously don't do and so I am just lost with what to do.
She's my 4th so its not like I'm new to this but I don't remember my others being quite so bad. She does get lots of 1:1 time doing things that she has chosen.
Any ideas would be great!
