A child seat has a seat base with a seating surface, a front edge, and a back end. A back support surface of the child seat is generally inclined relative to the seating surface. A seat bight is formed at the juncture between the seating surface and the back support surface. The seat bight is adjustable between a first bight position spaced a first distance from the front edge of the seat base and a second bight position spaced a second distance from the front edge of the seat base. The second distance is less than the first distance. A seat back insert can be provided that is attachable to the seat base in one or more insert positions defining one or more of the bight positions. The insert can create the back support surface at one or more position relative to the front edge. The seat base can also have a back wall creating the back support surface further from the front edge when the insert is removed.
