Well, first off, I always nap the younger ones in their own rooms in pack n plays. (infant to almost 2 yrs) once they hit two years or a bit over, they are ready to follow the "nap rules" lay still, stay quiet and stay there until all are awake. Once they are old enough to do that, they will use a nap pillow and sleeping bag and sleep on the floors (usually in the bedrooms) I have had as many as 4 sleep in one room before. (older ones) for about a year, I have been using bedroom for ALL the kids to nap, but before that, I only used the bedrooms for the babies and used the living room for the older ones, had as many as 6 sleep in the living room. Just found lately, I can enjoy my home and do all cleaning and get more done if all the kids are esleep in the bedrooms rather than out in the livingroom. Your biggets hurdle will be to get ALL sleeping during nap, after that it really is a matter of control. (and learning certain personalities) you have to figure which ones can and can't sleep near others. as far as having them ALL sleep in the same room...you may be attempting to bite off more than you can chew and may realize it will be much easier to utilize the bedrooms for nap time only, in order to have them separated and all get a good rest. Good Luck to whatever you choose, nothing is impossible, just may be more difficult.
