Why "shhh" calms a baby
A long, rhythmic shhh sits in the same frequency band as the whoosh of blood flow a baby heard in the womb, which is why it is the third of Harvey Karp's 5 S's. Done properly it is louder than the crying, close to the ear, and steady. Most parents run out of breath long before the baby runs out of tears — that is where a loop earns its place.
Record your own
Your voice is the one sound your baby prefers over every other. The Record tab captures a shush or a lullaby in a few seconds, and the recording sits on the Sounds screen like any other tile: loop it, time it, favourite it. Recordings never leave the phone.
FAQ
Shushing: questions parents ask
Why does shushing work on babies?
+
It mimics the constant whooshing sound of the womb, which is a newborn's baseline. It works best when it is steady and about as loud as the crying, then lowered as the baby calms.
Can I use my own shushing?
+
Yes. The Record tab saves your own shush or lullaby and plays it on a loop with the timer. Recordings stay on your phone.
Is a shush loop safe all night?
+
At a low volume and 7 feet from the crib, yes. Most parents use it to settle, then switch to white noise or let the timer fade it out.
