mine are all in different rooms and I have a few fans running here and there and they all sleep for 3 hours. if they wake up early they all know to stay quiet. but Judys right .....swoop in on them with your mean face and it wont take long. get some nap mats and put each kid in a different place ....hallways , living room, dining room, and the little ones each in a bedroom by themselves. you'll get your break soon enough.
