Baby Sleep Music with Heartbeat & Womb Sounds
For nine months, the loudest, most constant sound in your baby's world was your heartbeat. Baby sleep music built around a soft heartbeat hum taps directly into that — and pairs beautifully with a personalised lullaby on top.
1. Why the heartbeat works
A steady 60–75 BPM low-frequency pulse closely matches what babies heard in utero. The nervous system recognises it as "safe" and downshifts arousal — faster than most generic white noise can.
2. The two-layer setup
- Layer 1: heartbeat / womb hum — constant background.
- Layer 2: personalised lullaby with baby's name — the cue.
- Total volume under 50 dB at the cot.
- Speaker 1+ metre from baby's ear.
3. When it's most useful
Newborn weeks, the witching hour, contact-nap transfers, and the first hour of overnight sleep. Anytime baby needs that "back in the womb" reset.

Frequently Asked Questions
Does baby sleep music with a heartbeat actually help?
Yes, especially in the newborn months. A 60–75 BPM heartbeat-style hum mimics what babies heard in utero and lowers arousal quickly.
Should I play heartbeat sounds alone or under a lullaby?
Under a lullaby is best. The heartbeat regulates, the lullaby cues. Together they're more effective than either on its own.
Is it safe overnight?
Yes, played softly (under 50 dB) from a speaker at least 1 metre from the cot. Loop it as long as you'd loop any sleep cue.
When do babies grow out of it?
Most babies still respond to heartbeat-style audio well past 6 months — there's no need to stop. Some parents keep it as a layer for years.
