Cute toddler Joseph puts car safety first when he appears in the lastest Britax tv commercial.

He fought off stiff competition from other children to land the featured role promoting Britax's King Plus child car seat.

His secret to appearing so happy on set? The entire production team and his Dad sang Happy Birthday to him which raised smiles all round.
