This week's big developments: Your baby can now squint, frown, grimace, pee, and possibly suck her thumb! Thanks to brain impulses, his facial muscles are getting a workout as his tiny features form one expression after another. Her kidneys are producing urine, which he releases into the amniotic fluid around him — a process she'll keep up until birth. She can grasp, too, and if you're having an ultrasound now, you may even catch her sucking her thumb.
In other news: Your baby's stretching out. From head to bottom, he measures 3 1/2 inches — about the size of a lemon — and she weighs 1 1/2 ounces. Her body's growing faster than his head, which now sits upon a more distinct neck. By the end of this week, her arms will have grown to a length that's in proportion to the rest of her body. (Her legs still have some lengthening to do.) She's starting to develop an ultra-fine, downy covering of hair, called lanugo, all over her body. Your baby's liver starts making bile this week — a sign that it's doing its job right — and her spleen starts helping in the production of red blood cells. Though you can't feel her tiny punches and kicks yet, your little pugilist's hands and feet (which now measure about 1/2 inch long) are more flexible and active.
