DS1 goes to preschool a few days a week for 4-5 hours. He's the #1 cleaner-upper they have! (Or so his teachers tell me!)

He's the first one to start rounding up his toys and leading the other kids to clean up when the teacher tells them it's time for the next activity.

He also is great about cleaning himself up and his plate after snack time and lunch.

At home... he's not a messy eater, but definitely expects one of us to clear his plate (which we don't mind at this point since he's not tall enough really to put dishes away in the sink). And it's like pulling teeth getting him to put his toys away (most of the time)!
