While many fans of the Little House books know that Caroline Ingalls, with her husband Charles, had four children, all girls, that actually isn’t true. The girls were Mary, Laura, Carrie and Grace. But Caroline Ingalls also gave birth to a son, named Charles Frederick Ingalls, but he, unfortunately, passed away as an infant at only ten months of age.
Baby Freddy, as Laura called him, was not included in the original Little House books, although he is mentioned in the Pioneer Girl manuscript. He also appeared on the Little House on the Prairie television show, although not very accurately.
So in total Caroline had five children, four daughters and one son, although only the daughters survived to adulthood.
