S – upported back
In an upright carry a baby should be held comfortably close to the wearer so their back is supported in its natural position and their tummy and chest are against you. If a sling is too loose they can slump which can partially close their airway. (This can be tested by placing a hand on your baby’s back and pressing gently – they should not uncurl or move closer to you.) A baby in a cradle carry in a pouch or ring sling should be positioned carefully with their bottom in the deepest part so the sling does not fold them in half pressing their chin to their chest.
