Really depends on the child; great nappers? Currently I have my 3 great sleepers in one room (my son is one of the 3 and they all sleep in his room: Toddler bed, crib & pack n play). I have one other (3 1/2 yr old) in my spare bedroom (on the bed we don't ever use otherwise). My 2 babies are in pack n plays each in separate other rooms. Ideally I would love all of the older ones on cots in my playroom (babies can remain in pack n plays where they are). But, they sleep so well in the current arrangement I hate to mess with it (even with a pack n play in every bedroom!). My one baby is a screamer/talker all through nap time...not a good sleeper...don't see being able integrate him in with others.
