There's a new sheriff in town

I never had a playroom when I was a kid (I didn't have time to play, what with having to walk to school barefoot, in the snow, uphill both ways). When we found our house one of the big draws was a nice little room right off the kitchen and behind the living room which could serve as a playroom. A place for the toys to go, a place where they belong! So, I set to making it a darned cool playroom. I painted a border around the room and affixed bright primary colored wooden alphabet letters (I couldn't find a wallpaper that I liked, and I love copying things I see in Pottery Barn but paying 1/2 as much). We bought a table and 5 little chairs. I have labelled bins for every type of toy: Dinosaurs, Little People, Dress-up. There's a kitchen in the playroom, and a sit and spin, and all kinds of really cool stuff. When I was a kid I would have killed for a playroom like this. My kids? Not so much. It is a disaster area. It is so freaking messy that it gives me hives. Despite my careful mod-podgeing of labels, there are dinosaurs with little people, and little people in with the dress-up. Somehow, there's even dirty laundry in there. It makes me NUTS! I keep threatening that one day they will wake up and it will all be gone. I would do it too, if I could find the energy to pack it all up and put it all away after I struggle to get them in bed each night.
Hubby tries to help me keep it clean, but really, he just makes sure there is a clear path to the door in case of fire. Even he doesn't read my labels. So, every few weeks, MOMMY CLEANS THE PLAYROOM. This is a day that my children face with dread. One time I heard First Son say "Daddy, what IS she doing?" I get in there and dump every single container. I am a segregationist! NO Lego's with the matchbox cars! No princesses with the dinosaurs! And oh, there better not be crayons cavorting with anything but crayons!
Are my expectations too high? Do I ask too much? Well, at least for a few days after Mommy cleans up things tend to get put away correctly. I truly believe that kids need this kind of order. I find that when the playroom is clean, they play better. They play with toys and games that they haven't seen for a while. They make an effort to clean up. And, I am a nicer person when the playroom is clean. Well, Not that first day, because that day I am a bit sleep deprived, ya know?
