Make a very visible change in the kitchen.
Like bright table cloth, party bunting or anythingbright cheerful to be noticed.
This new item is hanging
Will she ask you or mention it?
When she does say
That’s right, we are changing and doing things differently. We have a happy kitchen now.
You address both of them.
What I’m doing is being mummy, and preparing and serving family meals that they will eat. We are speaking nicely and if we don’t like something, we don’t eat it. But there is not other food … other than toast with spread. If you don’t want the food, please politely request bread with spread.
Then the kitchen is closed.
These changes are also for bath, bedtime, in shops, in the car.
If any family member wants something, doesn’t like something, had anything to say - we all speak nicely, including mum. If you think I can’t hear you, please raise your hand like at school. No shouting.
Any shouting, we all stop talking. We go home. It’s all over .
Be sure you are also directing at the sibling.
And mean it.
She has to get zero zero zero attention. Just change your mummy face down to neutral, tidy up & walk away quietly and do some other task. Leave her screaming. And next time she makes a request for a thing, activity … I need to think about it. Did you follow the new rules on Sunday? Tell me what happened on Sunday. Make her say it.
Take no shit, but do it calmly.
