Miracle at daycare

What to my wondering eyes did appear was twenty small children napping quite near. HOW DO THEY DO THAT!!! It's like a freak of nature. I can't even get my toddler to nap by himself, but if you add one other toddler to play with, he'll never get to sleep. Yet there they all were napping peacefully on the floor in one room. Wow. I ask how they do that and she says "It works quite well." I see that it works, but how? She also tells me Sabian was one of the first to fall asleep and napped easily. My Sabian? I want to know where they hide the magic wand.
