I wouldn't volunteer the nap area as part of your tour. I would let parents know the kids sleep in their own playpen on the upper level in a private room. If parents insist on seeing the room, I would show them one bedroom, they don't need the grand tour upstairs, especially your bedroom. Or on the flip side, if you are dead set against showing the room, just say the room is occupied for personal use right now. I can show you during daycare hours. Hope this helps
