We thought at 9 step-DD2 would be too old for a 'good girl' chart but how wrong we were. She worked with it really well, at the top was something really special like a cinema trip or a DVD it was a long way up but within reach. At the bottom was 'miss x' dependent on what was planned that month be it a Brownie trip or a Birthday Party - she did NOT want to go there more than once that was for sure. We always followed though even if it was detrimental to the family after she once screamed 'you never make good on your threats anyway!' Mwhaa haaa haaa, did she regret ever saying that! We had stepping stones on the chart like 'fave pudding' vs. miss pudding, 'pocket money' vs. 'miss pocket money', 'watch a film of your choice with Daddy' vs. spend time alone in your room' and it did work.
We also worked out DD was stressed about the new school routing, homework etc and could not express it. Suddenly she was being exposed to too much responsibility and she did not know how to take it. We got a big wall chart and mapped out her week so she could easily see what was expected each week. After school time had homework, reading and TV clearly labeled.
It did seem to help, if she decided to make an entry into the 'eye rolling' world championships when I was asking/telling her what to do I would stop immediately, say Time Out, come back when you can be civil. If this was in the middle of dessert I would take it away with me and go to another room and sit and read. If it was in TV time I would turn the TV off and walk away with the controls. So, she either had to come and apologise or go without.
We also banned Nickolodeon and all rubbish US sitcoms like the Suite Life, Jake and Josh etc etc. Complete ban which is still in place, those programmes were just teaching her that bad behaviour is funny.
It was a long hard year but we do seem to be making progress. Now, if things look like they are going pear shaped I stop the converation immediately and walk away inviting her to come back when calm.
I spend days counting to 100, standing on the doorstep with a cup of coffee and my teeth chattering but the less we shout the less she shouts... naturally I know but bloody hard to carry out when they are being little mares.
Step-DD1 just shouted at her Mum, never me or DH so SDD2 had to live up to her 'angelic' older sister and then I had a baby! She is anaphylactic to nuts and struggles with her weight making her a target at school.
Poor child, it is hardly a wonder she does not cope sometimes!
