Cutting down on sibling bickering will not only make your house more peaceful, but it will also help your children develop loving relationships with each other. Use iMOM’s sibling rules like this: First, post them. Praise good sibling behavior when it happens by pointing to it on the list. When a child isn’t acting nicely, you can ask, “Is that kind of behavior on our do list or don’t list?” Let them walk over to the list and see for themselves. If they’re too young to read, point it out for them.
