great expectations, 2

Things are progressing normally with the baby.  Here is today's email update from "What to Expect When You're Expecting": 

WEEK 16: NOW HEAR THIS

Listen up: Tiny bones in your fetus's ears are in place this week, making it likely that the baby can hear your voice when you're speaking (or singing in the shower). In fact, studies have found that babies who are sung to while they're in the womb recognize the same tune when it's sung to them after they are born (so choose your baby Muzak with that in mind…). And baby's busily boning up in other ways. For one, the backbone (along with the back muscles) is stronger now — strong enough, in fact, to enable your baby to work on straightening his or her head and neck even more. Baby's crown-to-rump measurement is between four and five inches in length, and weight is hovering around three ounces. 
This little one's a looker — with a face that has both eyebrows and eyelashes — but a skinny looker since there's no baby fat yet. And here's the skinny on baby skin: It's practically translucent now, so if you took a peek inside your uterus, you'd be able to see your baby's blood vessels under that thin skin.
