Walkers serve different needs at different stages of life. Mobility walkers give people added support for balance and movement; some have wheels for rolling along, while sturdier designs are made to accommodate greater support needs. Child-sized walkers are used as young children learn to stand and take steps. Some are push-along carts or toys, while other baby walkers are designed around a seat and frame. These forms differ in how they support movement, but all are associated with getting around on foot-with assistance from a frame, wheels, or a push handle.
