I am looking back today not to my ancestors, but to my son. He turns 21 years old in a few days! Is a 21-year-old photo old enough to count as a throwback? Here is his first baby picture. This was taken a day or two after he was born, but was not the official hospital photo; he never had one of those. The photographer was photographing in the maternity ward when he was in the NICU, and in the NICU when he was in the maternity ward. So I took one myself. He weighed 6 pounds. Now, as a college junior, he is 6-foot-three.
