When my kids fight over toys, I tell them we have to "sun bleach" them so all the fight inside of them is replaced with sunshine.

Specifically, I have them place the toy in the window or wherever there is direct sunlight for 5 minutes. Now whenever they feel the urge to start fighting they both volunteer their toys for the "sun doctor" right off the bat. They've even started incorporating it into their play.Highly recommend. via /r/Parenting https://ift.tt/2QgcSEj
