Buckle carriers, (also known as "soft-structured" carriers, or SSC's) are very much like frameless backpacks, with soft padded shoulder straps and a wide buckled waist belt for added support. The designs of Love & Carry® ONE+ and AIR X baby carriers meet the standards of International Hip Dysplasia Institute by having the carrier reach to baby’s knees while baby's hips are being spread in physiological "frog-like" position. Love & Carry® ergonomic baby carriers wrap the baby around, providing a nice hold and great support while keeping the baby in a healthy position. Thanks to its snugly fit, a soft baby carrier puts no load on the baby's perineum and lower part of the spine. Due to its features, the Love & Carry® ergonomic baby carrier is an excellent alternative to traditional slings and carriers.
