First of all can I just say how much, i have enjoyed reading this thread. As this is a daily struggle in our house. We are currently redoing my daughter’s room and employing many of these strategies. In our case my daughter loves the color pink,so I bought a bunch of pink containers to help encourage her using them. This included some tubs to put things into storage. Since there was a variety of items she no longer plays with, but the thought of getting rid of them was causing massive meltdowns. For the containers in her room she was in charge of deciding what goes into each container. We are still in the process of cleaning out her room, but so far the amount of stuff leaving her room has been quite rewarding.
