Most people are unaware that the actresses started working on the show at a very young age. For example, Kim Fields was only ten years old when she landed a role on The Facts of Life, whereas Mindy Cohn and Lisa Whechel were 13 and 16, respectively.
We had no idea the girls were only 13 years old when Nancy McKeon joined in season 2! We knew they were young, but we hadn’t realized just how young ten years old is. It seems like yesterday we barely knew more than home and school ourselves, let alone a television set and cast.
