To ask how do "make" a child do something?

[littlegoblins]

My child has got into their siblings bed and is refusing to move, other sibling is waiting to go to bed but they won't get out, I've asked sternly and they say no everytime I say get in your own bed.
Actually other child would probably swap beds for the night to stop all this but I don't want them to always back down to a child that is disobedient. Child in question is just 6. Sibling is an older 6, nearly 7.

It will, playdate is weekend, its Monday today

Yes I agree with you @Coyoacan

The other child is only 6 too, what messages is she getting when mum can’t get her own bed back for her, and her younger sibling gets to displace her?

Just checked on them on my way to bed, both fast asleep looking like butter wouldn't melt.

It's funny how much you love them when they're asleep 😂.

This. I was just about to say. Behaviour is communication. Discuss, find out the whys, resolve the problem together, explain the consequences of the behaviour (not the consequences you would give - but why it isn't appropriate) Strange how most people have jumped straight to punitive measures 😧
