Absolute quiet provided by a white-noise sound machine, plus darkness provided by blackout curtains, was/is crucial in helping my toddler get healthy, successful naps. Without them, he would not be able to sleep with the afternoon sun pouring in the window while listening to Mom and Dad putter about the house. It does make me worry how we'll wean him off the sound machine.
