Our patent-pending support belt makes it easier to carry heavier babies and toddlers. It is compatible with the pikkolo carrier as well as our mei tai (and most brand mei tais).You simply thread your carrier through the belt and leave on for a more traditional padded SSC-style waistband. You may wish to add the belt when your baby reaches 20+ lbs. We recommend placing the belt on and leaving it, not switching it on and off frequently. THIS IS A BELT ONLY, NOT A CARRIER. MUST BE USED IN COMBINATION WITH THE PIKKOLO CARRIER OR A MEI TAI CARRIER. Made By: Catbird Baby Made Of: 100% Cotton
