Robinson's childhood home was on the upper floor of 7436 South Euclid Avenue in Chicago's South Shore community area, which her parents rented from her great-aunt, who had the first floor. She was raised in what she describes as a "conventional" home, with "the mother at home, the father works, you have dinner around the table". Her elementary school was down the street. She and her family enjoyed playing games such as Monopoly, reading, and frequently saw extended family on both sides. She played piano, learning from her great-aunt, who was a piano teacher. The Robinsons attended services at nearby South Shore United Methodist Church. They used to vacation in a rustic cabin in White Cloud, Michigan. She and her 21-month-older brother, Craig, skipped the second grade.
