Step-by-step guides from the maker's manual. Pick one.
Harness
1Loosen the harness by pressing the harness adjustment button firmly while pulling both straps forward at shoulder level.
2Press the red buckle button, open the chest clip and spread the straps apart.
3Sit your baby with bottom in the seat and back fully supported; gently straighten newborn arms and legs, minding sensitive spots like the belly button.
4Bring the straps over the arms and shoulders with the buckle between the legs, then click each tongue into the buckle.
5Click the chest clip, pull the adjuster strap to tighten, and keep the chest clip even with the armpits.
The maker warns:
The shoulder straps must come from the closest slots at or below your baby's shoulders; this seat changes strap height by rethreading, so do it with your baby out of the seat.
When do I use or remove the Cybex Aton 2 infant insert?+
Use the infant insert for a better harness fit and more head and upper body support for small babies. Cybex recommends it until 22 lb or until your child needs more room; take it out if it pushes the head forward or spoils the fit.
