There are some rules of thumb to follow for the comfort of both the baby and the parent:
1. Put on the baby carrier like a shirt over your head.
2. Place the back yoke under the shoulder blade and then attach the waist belt to the back. For maximum comfort, the waist belt should be up on your waist and not low on your hips.
3. Loosen the shoulder strap and unbutton the headrest on both sides as well as the safety lock on the side.
4. Put your child in the baby carrier. Once he or she is in place and you have locked the safety lock, buttoned up the headrest and, if applicable, the leg straps, you can adjust the shoulder strap and waist belt (so that it is comfortable for you and your baby).
