Originally the term characterized the bulk of the Middle Ages, or roughly the 6th to 13th centuries, as a period of intellectual darkness between the extinguishing of the "light of Rome" after the end of Late Antiquity, and the rise of the Italian Renaissance in the 14th century. This definition is still found in popular usage, but increased recognition of the accomplishments of the Middle Ages since the 19th century has led to the label being restricted in application. Since the 20th century, it is frequently applied only to the earlier part of the era, the Early Middle Ages (c. 5th–10th century). However, many modern scholars who study the era tend to avoid the term altogether for its negative connotations, finding it misleading and inaccurate for any part of the Middle Ages.
I was going to use the term middle ages but most people understand what “dark ages” refers to. Since my comment was actually how babies were treated during that time, and not about the correct usage of the name, I think you are a little over the top sending me a lecture on the correct terminology for the “dark ages”.
