Was Molly Ringwald on Little House on the Prairie?

Molly Ringwald is probably best known for her roles in the 80s Brat Pack movies, such as The Breakfast Club, Sixteen Candles and Pretty in Pink.  did she appear on Little House on the Prairie?

During the time that Little House in the Prairie aired, she did appear on another television show, The Facts of Life. Ironically, although she is arguably the best-known of all the cast members to ever have appeared on The Facts of Life, aside from George Clooney, she was replaced after the first season when the show was reworked for its second season. But she did not end up appearing on Little House on the Prairie during the same era though.
