  • Patent number: 7182351
    Abstract: A crawling aid for infants having a partial disability provides a cushioned platform to support the body of the infant. The platform has wheels, including at least one caster, to render the platform maneuverable. Portions of the platform are narrow to allow the infant's good limbs to extend down and engage the floor; and, the head support allows the infant to see on both sides of the platform. Thus, the infant can execute crawling motion while body and disabled limbs are supported on the platform.
