With 19 weeks down, you're entering pregnancy month 5.
Your Baby at Week 19
At half a pound and six inches long, your baby is about the size of a juicy mango. And that’s pretty sweet!
On the development docket this week: a total baby body wrap. Your little one gets a head-to-toe coating of vernix caseosa, a white cheesy-looking substance made up of lanugo (that downy hair), oil from his glands, and dead skin cells. Maybe not a recipe for your favorite spa treatment, but just the right one for your fetus.
This waterproof mixture protects your baby’s skin from his 24/7 bath — the amniotic fluid — and lubricates the birth canal. Without it, baby would look positively prune-y at birth and would have a much tougher time getting out the door. Don’t be surprised if you see vernix remnants on your newborn right after delivery, especially if he makes an early debut.
On the looks side, your baby’s monkey-like appearance of yester-week is yesterday’s news now that his legs have gone through a growth spurt and are finally in proportion to his arms. Those longer legs, coupled with the strengthening of cartilage into bone, will make your little one’s kicks and jabs more powerful.
Add to that the newly-formed neurons that are sending better commanding messages from the brain to the muscles and you’ve got a formula for stronger, meaner, and more controlled movements, allowing your acrobat to take his body for some serious test-drives — and for you to start feeling them. In the coming weeks you’ll experience plenty of flutters, kicks, jabs, twists, stretches, and punches. And no matter when you begin feeling them or what they feel like, all your baby’s movements are bound to be moving.

How big is my baby at 19 weeks?
Six inches long this week and just over a half pound in weight, your baby has gone through a bit of a growth spurt.
Your little one may have a cheesy varnish this week.
Say what? You read that right — a protective substance called vernix caseosa (vernix is the Latin word for "varnish"; caseosa means "cheese") now covers your fetus' skin. It's greasy, white and made up of that downy hair known as lanugo, oil from your baby's glands and dead skin cells.
This waxy "cheese" may not sound too appealing, but it's there for good reason: Vernix protects your baby's sensitive skin from the surrounding amniotic fluid. Without it, he'd look very wrinkled at birth — sort of what you'd look like if you soaked in a bath for nine months.
The vernix sheds as delivery approaches, though some babies — especially those born early — will still be covered with it at birth, so you might get a look at your baby's first anti-wrinkle cream.
