I am still packing on the pounds — at the rate of about an ounce a day. I now weigh almost 6 pounds (like a crenshaw melon) and I am about 19 inches  long. I am shedding most of the downy covering of hair that covered my body as well as the vernix caseosa, the waxy substance that covered and protected my skin during my nine-month amniotic bath. I swallow both of these substances, along with other secretions, resulting in a blackish mixture, called meconium, which will form the contents of my first bowel movement.
