The Baby Ktan is an innovative ready to wear wrap. Its unique double-loop design functions as an all-in-one sling, wrap and baby carrier, yet does not require any wrapping or buckling. Simply slip it on like a t-shirt! The Baby Ktan is sized like clothing for the perfect fit (XS, S, M, L) and offers multiple positions from 8-35 lb (consult physician for preemie).
