Well first I don't do bus runs for the exact reason that its stressful .... But I'm assuming its for your own kids so not really a choice.... Second everyone in my daycare naps ... Not negotiable !!! If they choose not to sleep that's find but they must stay in the cot and be quiet. I must admit I'm finding my days much easier since my youngest started full day jk in sept so now its just the daycare kids. It doesn't bother me if someone wakes up during nap ... I have fans running to drown out some of the noise and I just ignore. You could always use an iPod if you have one and pop in the ear buds and listen to some music. Just sit back and relax
