Charles Fredrick Ingalls 'Freddie' started losing weight at nine months.
Despite the Doctor being called, he couldn't do anything about it and Freddie died. Apparently allot of baby's had the same in those times and nobody knew how to cure it. I don't know what the disease was called though.
Added later by another member:
Charles F. Ingalls Jr. died just 3 days short of his 10th month aniversary. Since there seems to be no recorded symptoms of his illness there could be any number of causes for death, some of which are not common today. Babies still pass away from viruses in modern times although it is not usual now; and there is "failure to thrive"...since diet was more limited in those days it may have been related to a nutritonal deficit or some intestional problem. It's sad, but very likely the doctor had no idea what was wrong...
