33.5 weeks

Your baby kind of looks like she's coated in a layer of cream cheese these days. The thick, white substance that protects her skin from pruning in the amniotic fluid is called vernix. When she's born you'll probably see some vernix lingering in her "hard-to-reach" places like under her arms, behind her ears and around her va-jay-jay, if she's a she.. Other news from the womb this week:

The soft fur, lanugo, that covered your baby's body for much of her stay in the womb is now almost completely gone. Your baby begins to develop her own immune system, instead of relying solely on antibodies received through the placenta. This will come in handy when some grubby relative manhandles the baby without washing his hands first.

This week, your baby measures about 17¾ inches, as almost as long as an American Girl Doll (!) and weighs almost 5 pounds, as heavy as a bag of sugar, minus the cup you put in your decaf this morning.
