I have the same set-up...I use my kitchen and we all sit at the dining room table to eat together. Main floor powder room is the "potty room" LOL and I have a laundry room right off it that I change diapers ontop of the dryer - saves my back! My daughter has her own room and pack n plays in guest room + 1 in my room....if I get another older child they will share the guest room..the "good sleeper"'s room LOL
