During the 1970s, McBain slowed her career somewhat to care for her son Evan, though she continued to make guest appearances in a number of television series. "I never really cared about superstardom, I only cared about the roles that were available to those who were superstars," she later said. "I was motivated to continue on in the face of total failure because I had a child to rear on my own with little help from his father. Acting was the best way for me to make money and the best way for me to be a more present mom in my son's life. Full-time jobs brought in money but kept me away from the day-to-day life of my child."
