COO - Baby Sound Therapy

For the sleepless nights and the love that fills them. Settle your baby by settling yourself first. Try Premium free for 7 days, no card required.

Some nights you're pacing the hallway, the backyard, the whole neighborhood with your crying infant, running out of ideas and running low on yourself.

COO was built for that moment.

It's a sound companion for parents and caregivers - layered audio designed to help you settle your baby by first settling yourself. When your nervous system regulates, your baby's follows. This is co-regulation: the science behind every instinct you already have.

Six sound environments, each designed for a specific moment:

• Calm & Settle - for the everyday overwhelm
• Big Feelings - when emotions are running high
• Bonding - skin to skin, fully present
• Immune Support - frequency support during illness
• Teething & Comfort - for the hard nights
• Sleep Wind-Down - the long, slow drift into rest

Each playlist layers pink or brown noise, a binaural drone tuned to a Solfeggio frequency, a heartbeat at 68 bpm, and a soft melodic overlay, set at a comfortable default volume for each layer.

COO Premium unlocks all six playlists, the sound mixer, Play All with a drag-to-reorder queue, and extended sessions for an effortless hands-free experience. Try all of it free for 7 days, no card required, then keep it for a one-time $3.99 whenever you are ready.

Made for caregivers, by a caregiver.
