A familiar heartbeat for newborns and babies
A soft, steady heartbeat with a womb-like bed can feel familiar to a newborn and help some babies settle
Play a heartbeat nowFor roughly 9 months before birth, a baby lived inside a fairly noisy place. The maternal heartbeat thumped steadily nearby, blood moved through large vessels with a soft whooshing sound, and everything arrived muffled through fluid and tissue. That low, rhythmic background was constant company. So when a newborn meets a quiet room for the first time, silence can feel less reassuring than the steady pulse they grew used to.
A synthesized heartbeat tries to recreate that texture. Set to a calm 60 to 70 bpm with the womb background bed turned on, the generator gives a soft lub-dub wrapped in a gentle, muffled hush. It is not magic, and it will not work for every baby. But many parents find that a familiar, predictable rhythm helps some babies settle, especially during fussy evening stretches or the slow wind-down before sleep.
Treat this as one tool among many. Feeding, a clean diaper, gentle motion, swaddling where appropriate, and a calm adult all matter at least as much as sound. The heartbeat is simply a low-effort thing to try.
A steady 60 to 70 bpm pulse echoes the muffled heartbeat a baby heard before birth.
The soft background whoosh adds the muffled, enveloping quality of the womb.
A low, constant sound can soften small household noises that might otherwise stir a baby.
A few small choices make the heartbeat more soothing and, more importantly, keep it safe:
Sound for babies is helpful only when it is used carefully. The most important points come straight from American Academy of Pediatrics guidance on infant sound machines:

For about 9 months in the womb, a baby was surrounded by the muffled rhythm of the maternal heartbeat and the whoosh of blood flow. A soft, steady heartbeat at roughly 60 to 70 bpm, with the womb bed turned on, recreates a familiar texture. Many parents find it helps some babies settle, though every baby is different and it is not guaranteed to work.
Follow American Academy of Pediatrics guidance: keep the sound below about 50 decibels and place the speaker or device at least 7 feet from the crib, never in the crib. Keep the volume low, point it away from the baby's head, and turn it down if you have any doubt. Quieter and farther is always the safer choice.
A calm, resting range of about 60 to 70 bpm works well for most babies, which is why the Resting (60) preset is a good starting point. Turn on the womb background bed for the soft, muffled quality of the womb. Watch how your baby responds and adjust slowly; some settle better at the lower end near 60 bpm.
Many families use the sleep timer so sound plays while the baby drifts off and then fades, rather than running loudly for hours. If you do leave it on, keep it quiet, below 50 decibels, and well away from the crib. Always follow safe-sleep guidance: baby on the back, on a firm flat surface, with nothing loose in the crib.
