How do I adjust the Ergobaby Omni 360 baby carrier seat to my baby?s size?

Published in Omni 360
The Ergobaby Omni 360 carrier adapts to your growing baby in just one step. Adjust the seat using the velcro tabs on the waistbelt based on your baby's height: along the red lines for a baby between 20-24 inches / 50.8-61 cm (~0-3 months), along the yellow lines for a baby between 24-28 inches / 61-71 cm (~3-9 months), along the blue lines for a baby over 28 inches / 71 cm (~9 months +).
