It is your responsibility to keep your baby safe. Use common sense and double-check your knots.

Spread the carrier out on a bed, lining facing up. Lay your baby down on top of it. Make sure very young babies have their heads adequately supported by the top curve of the carrier.	Sit and either froggy up a newborn's legs against your back, or spread an older baby's legs around your waist.	Tie a firm square knot around your waist.	Reach back and grab one shoulder strap
and then the other.	Lean back and slowly pull the straps up to meet your shoulders.	Rock yourself forward while holding baby against your back.	Stand and lean forward a bit. Taking all the slack out of the straps helps seat baby higher.
Cross straps across your chest, over baby's legs, and around the back.	Cross back to the front, under baby's legs, and tie a secure square knot at your waist.	OR, bring straps up and over your shoulders, and straight down under your armpits, to wear the straps like a backpack (rucksack carry).	Again, cross straps behind baby's seat, bring back to the front, and knot firmly at your waist.
