B.C.
Bins, baskets and shelves! We have a toy organizer thing in my DD's room with labels on them saying what goes in. There are 12 and here's how I broke them down: Dollhouse stuff (takes up the bottom two bins), balls, toy cars, baby doll stuff, small toy animals (takes up 2 small ones), doctor toys, tea party stuff, and toy food. Then, we have baskets for the littlest petshop stuff and they live on a shelf along with her LPS houses. Dressup stuff has a box that also lives on a shelf. She has another bookshelf that houses a toy castle, barbie car and barbies, and some smaller popular toys and books.
What doesn't get picked up before bed goes in a basket that will sit outside her door until the a.m. (she calls it "mail", lol).
And, I'm always getting rid of things too.
