I sometimes have to threaten the kids, but they pick up their own messes. My rule is if I have to pick up your toy, it goes straight in the trash. Believe it or not, my 7 yo loses more toys than the 22 month old. They are in the playroom cleaning now. If they don't have it clean in the next 30 minutes, I'm going to cancel our afternoon plans. I can't function in a messy house.
