Oxford what world do you live in,
DCs need to get to school, there siblings need to get to school, there parents need to get to work.
If that means a jug of water or a slap on the backside so be it.
Sometimes there is time for perfect to the book parenting and sometimes there simply isn't.
You can negotiate star charts and rewards at 5pm, you can't at 8.30 am.
DD2 went through a phase of deciding the world revolved around at about 9 or 10.
I remember finally loosing it and telling her she was a selfish bitch.
Not nice and I'm not proud of myself, but her big sister didn't need to be waiting around while she faffed. (I can't remember where we were going. Not school, she hated being late for school and nagged everyone else).
Later we talked and she said she didn't like being called names and I agreed that I shouldn't, but I did finally get through to her that there was a limit to everyone's patience.
No she didn't get better overnight, she's almost 12 and gradually in the last year she's got better.
Their Y6 teacher was supper and understood how to give them a bit of independence and roles to fill.
I'm happy for her to go to the shop or stay home for the odd hour and she no longer feels quite so pushed about.
I was very naughty at school in Y5 mostly because I was bored to tears.
In Y6 we were streamed and DDad let my cycle to town, so I understand why this age is so hard.
Understanding doesn't necessarily mean you handle things perfectly, especially when DD1 is a much less firery character than me, DH or DD2.
