WHY LULLABIES Lullabies calm infants (and parents), and the research is absolutely clear about it.

In a study of 144 infants published in Nature Human Behaviour (Bainbridge et al., 2021), babies relaxed to lullabies - even from cultures they had never encountered. Heart rate fell, pupils narrowed, and skin-conductance measures showed reduced excitement. The songs were unfamiliar and foreign, which suggests infants respond to acoustic qualities shared by lullabies everywhere, not only to songs they already know. The effect held over 12 months of regularly listening to lullabies.

EEG work has also traced that response into the brain sensitivity: seven-month olds tracked their mothers' singing more closely for lullabies than for livelier songs, with the acoustic qualities of the singing shaping the neural response (Nguyen et al., Developmental Cognitive Neuroscience, 2023).

Nina is built to those shared qualities: slow tempo, steady rhythm, soft low tones and no sudden changes in volume.

WHAT'S INSIDE • 36 tracks across four moods: Calm & Relax, Deep Sleep, Womb Sounds, and Bedtime Routine • Womb-inspired rhythms: the steady, enveloping sound babies know from before their birth • Gapless looping: tracks flow seamlessly for as long as your baby needs, with no pause that break a light sleep phase • Sleep timer: 15, 30, or 60 minutes, ending in a slow one-minute fade rather than an abrupt stop • Plays with the screen off and in the background, all night if needed

HOW NINA IS MADE Nina's music is enhanced with AI under human direction: using slow tempos, tracks that sit at a natural and calming 60 beats per minute, close to the resting heartbeat a baby hears in the womb, soft low tones, no sudden changes in volume, and none of the bright, brittle highs encountered with other white noise/sound machine/apps.

FOR YOU - THE PARENT - TO ALSO RELAX Research on lullabies in infant care also applies to parents: the music lowered the parents' stress, anxiety and frustration levels (Loewy et al., Pediatrics, 2013). Nina is for the person holding the baby at 3am as much as for the baby.
