K.S.
I get my four year old son to do it. We go into his room. He clambers up into the top bunk and pulls the old sheets, the comforter, and the pillow off of the bed and tosses them onto the floor. I toss up the clean sheet and he hooks the bottom sheet over the corners I can't reach from the floor. I hook them over the corner I can reach. I toss up the top sheet and help him get that into place. Then I toss up the comforter and the pillow. He's a great little helper!
