Size Guide - Stage 1

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.
