Sounds for babies

Parents tend to keep a small set of sounds for bedtime, and they are usually slow, soft and familiar. Lullabies on a music box, harp or piano mark the end of the day. A heartbeat or a gentle shush gives a steady, quiet floor, and plain white noise works in a similar way. A calm purr is another choice. Pick a few and use them in the same order each evening, so they become part of the routine. As common-sense guidance, keep the volume low and the device across the room, away from the crib, and use a timer so the sound does not run on all night. If you are unsure, ask your pediatrician.
