Maybe she had bad reactions to the hypnotic medications they used to give back then for labor. There was quite a trend to give women something called "twilight sleep" during labor and then put them out under general anesthesia during the actual delivery. It was usually a medication called scopalamine. It had no pain reduction properties, but it gave women amnesia. In other words, they hurt like hell, but couldn't remember it later, and they were often delusional and wild during labor.
