* Your baby now has fingerprints! Book 'em, Danno! Believe it or not, he actually created them himself while swimming around in the amniotic fluid. As he moved his hands, the skin on the tips of his fingers formed unique ridges and folds. That's why no one on earth has the same fingerprints, not even identical twins! Cool, right? Baby's arms are now in proportion to his tiny body, but his legs are still on the short size in comparison.
* Your baby continues to gain new and impressive skills such as practicing and controlling voluntary muscle movements (this will help him fling food across the room later in life). Your tiny dancer's movements are no longer the jerky, uncontrollable twitches of yore—he now moves with graceful control.
* Your baby now weighs about an ounce and is the length of a flip phone, or roughly 3 1/2 inches—he's tripled in size from a mere three weeks ago! Luckily, you haven't done the same.
I am feeling great this week, I noticed I get pretty nauseous when I take my prenatal vitamins so I might talk to the doc about that in a couple weeks. Otherwise all is good here!
