It drives me crazy when I see a floor full of toys, I really can't relax in a room like that. So I figured out this rule: no more than one box of toys on the floor. We don't open up another box until the first one is cleaned up. I have a boy - so small cars are in one large container, trains are in another, puzzles are in another one. To speed clean up - I start a game, we throw one toy each in the box, taking turns, or play who will be first to clean up - so far works like magic, the floor is clean in under 5 minutes and my stress level goes down drastically :).”
