Twenty Weeks Pregnant - HALFWAY THERE!

I weigh about 10½ oz now. I'm also around 6½" long from head to bottom, and about 10" from head to heel. A greasy white substance called vernix caseosa coats my entire body to protect my skin during its long submersion in amniotic fluid. I am swallowing more, which is good practice for my digestive system. I'm also producing meconium, a black, sticky substance that's the result of cell loss, digestive secretion, and swallowed amniotic fluid. This meconium will accumulate in my bowels, but you'll see it in my first nappy! And what are these tiny hard things on the end of my- my... well I suppose I’d better start finding names for things if I want to make any headway in what for the sake of what I shall call an argument I shall call the world, so let’s call them my feet. Anyway, little hard things on the end of my feet. I'll call them, er... nails. Is that a good name? I can always think of a better one later, when I've found out what they're for because there certainly seems to be a hell of a lot of them!
