This was a short-lived show on NBC (ran for 33 episodes in 1988-89). It was about Brian and Kate Harper, a professional couple (Doug Sheehan from Knot's Landing played stockbroker Brian, and Linda Kelsey from Lou Grant played lawyer Kate) who decided to open an in-home day care center. Their teen son Ross was played by C.B. Barnes, who played Greg in the Brady Bunch movies and starred in the Starman TV series and Malcolm and Eddie.
But I'd like to talk to you about the two other females in the cast. Two that went on to much bigger things later in their careers.
