20Make Them Wrestle You For A Precious Object
Children love playing games, and Hand in Hand Parenting suggests an absolutely awesome one.
They write, "This game is perfect to play when two siblings are [arguing] over a toy. Pick up a book, cushion, or any object that isn’t really too precious. Tell your children it’s your precious object that you never
want to let go of. Hold it really tight then let them wrestle you for it. Repeat with a different object so each child gets a turn grabbing something out of your hands."
This is so sneaky that kids will have no idea that you're helping get rid of any conflict and tension.
