I'm going to force my 5 year old to sleep in her own bed
What is causing you to force her to leave your bed?
I want to sleep by myself, kids are so stubborn.
It is important that children learn to sleep in their own bedroom at some point. While this may be difficult for the parents to get the children to agree, eventually it will be worth the efforts.
I know she'll cry, but she needs to grow up.
They'll get over it eventually. Try to remind them that part of growing up is doing things for yourself and by yourself. They'll want to be more like an adult and accept that sleeping alone is a part of that.
