The fit should be snug

A snug fit around the arms and torso helps calm the Moro/Startle Reflex. The neck hole should fit closely and comfortably without being restrictive (you should be able to get 1 to 2 fingers in the neck hole). The neck hole must not be able to pass up and over the baby's mouth. For the best fit, please select the size based on your child's weight, not their height or age.

Arms up Design

More sleep from Day 1

Our signature arms-up design supports natural self-soothing and has been shown to help increase average nightly sleep from 3h 45m to 7h 25m.
Natural Womb-Like Comfort

Just like being held, without the wake-ups. The arms-up position mimics the natural womb posture, helping babies feel calm, secure, and comfortably settled for longer stretches of sleep.
Self-Soothing Made Simple

So they can settle themselves, safely. Babies can bring their hands to their mouth to self-soothe, helping reduce startle reflexes and supporting longer, more restful sleep.
