There is no evidence to suggest that Laura Ingalls Wilder had any miscarriages. There is no known written accounting or mention of any miscarriages, but since women did suffer miscarriages frequently during this era – or miscarried early before they confirmed pregnancy – and it was something usually kept very quiet and not openly discussed, it is not uncommon that no mention of this was made.
During this time period, many women often had multiple pregnancies, and many infants did not survive due to complications during childbirth or from illnesses that were difficult to treat. While there is no record of Laura having a miscarriage, it’s possible that she experienced one or more losses that were not recorded in historical documents.
However, Laura and her husband Almanzo did experience the loss of a child. Their son, who was born prematurely in 1889, died just a few weeks after birth. This was a devastating loss for the couple, and it is believed to have been a major factor in their decision to leave South Dakota and move to Missouri.
