My girls sleep upstairs in their rooms while the rest sleep in the daycare in the bsmt. I do what the ladies above mention. My 3 yo's are fine to pick the books for their cots while I run the little one up and the almost 2 yo goes in his play pen until I come back. The baby just gets put in the crib and I say good night. She is used to the routine now. When nap time is over, I get my baby first and bring her down before getting the others up and out of their PNP/cots
