Abstract: A child support structure fits inside the child seat portion of a typical shopping cart. The child support has two primary elements; a horizontal platform or table that extends across the top portion of the shopping cart seat at approximate chest height, restraining the child from falling within or from falling or climbing out of the shopping cart seat; and, an upright wall-like teething guard to prevent the child from contacting parts of the shopping cart with his or her teeth or mouth. The preferred embodiment is made from a sheet of stiff plastic which is cut out and bent to form a squared C shape platform with folded over side extensions for the legs and an upwardly turned portion of the closed side of the platform as the teething guard. The bottom portion of the legs are further bent to form tabs or feet for resting on the bottom ribs of the shopping cart seat, and the top portion of the teething guard is bent to form a lip.
