In 1965, Tyler, then 11, was cast as a series regular in the TV adaptation of Jean Kerr’s 1957 novel "Please Don’t Eat the Daisies," playing Kyle Nash, the eldest brother to twins Trevor and Tracey (Jeff and Joe Fithian) and middle child Joel (Brian Nash). The parents were played by Mark Miller and Patricia Crowley, in roles originated by David Niven and Doris Day in the 1960 film version.

Tyler left acting after the series’ two-season run.
