Children outgrow baby back packs when they become toddlers. Parents usually have no alternative but to carry their children causing shoulder, hip and back pain. A parent himself, Jeff Bryce invented the piggybackpack. It is meant for children ages 2-9, by transferring weight load to the wearer’s waist, a child conceivably up to a couple hundred pounds can be carried. Bryce has sold hundreds through his website to parents that want to continue that close bond with their child without the discomfort.
