My daycare uses the entire house, but it really only seems to show in the basement where the "official" playroom is. They sleep upstairs, but I made a promise to myself that when my kids get home their rooms look only like their rooms so the 3 mats I use (crib mattresses) fit perfectly under my bed and the playpen is always folded up at the end of the day.

On my main level they have 2 wicker baskets...1 with books and 1 with individual quiet toys like the good old Leap Pad and Winnie the Pooh phone....stuff they sit and play by themselves. This way when they are upstairs, while I'm preparing meals or clearing away after, they are playing nicely.

I do get tired of gates and locks on everything, but I try to deal with it. I try to think about going out and getting a job instead. Then I don't mind....too much
