A weighted car seat pad includes a generally U-shaped main body having a pair of side protrusions that define a recessed buckle area. A retention strap extends across a portion of the recessed buckle area, and an opening is disposed along one side of the pad. A weighted pad insert is removably secured within the main body, and includes a specific weight that is matched to the age group and/or particular condition of a child with whom the pad will be used.
