Hug n Hold (formerly Change-eze) also works well as a shopping cart support to keep a baby from falling over in the cart seat.

Works well with children who have poor sitting balance, and are delayed with their muscle control.
Always supervise children. Older children can unfasten the velcro.

Just put the Hug 'n' Hold on to your child, and fasten the back strap with the buckle through the slats on a
grocery cart seat. Tighten the straps, and the Hug 'n' Hold will keep your child from falling over, falling forward,
or trying to stand up in the cart seat.
