I'm not saying this from any knowledge base other than my own kids, but I just have had no worry about one of them falling asleep on top of the other and smothering him/her. They've been big enough to move themselves around in the bed for a long, long time.
Do you put them to bed at the same time, and share the same sleep routine? About what time do you put them to bed? (Ours wake up around 530-630 because both Mom and Dad work). Thanks again!!
My older two (son 14 and daughter 11) like to sleep in the same room as much as I'll allow, but for them it is a bit like a sleep over and they get very silly and take forever to settle down. She does better sleeping alone and he does better sleeping on my bedroom floor (which we are trying to wean him from!)
