Solved My Toy Problem for Now

Our playroom is over run with toys. There is constantly a mess with the majority of the toys in the floor. When we had big toddler toys, clean up was quick and easy, but now all of the toys are microscopic and the kids are getting lazy. Lately Jaelyn has taken to dumping every bucket of toys into the floor. She thinks it's a game and Caden has joined in on it. I heard them tonight and sent a very upset Caden up the stairs with his sisters (who were very indifferent) while I took 2 large laundry baskets and put every toy on the floor in them. They are now locked in our spare room until I can get new tubs and then everything is going in the storage closet until they can prove to me they can play nicely and clean up after themselves. How do you teach kids to respect their belongings because mine certainly dont!
