This week's big developments: Your baby can now squint, frown, grimace, pee, and possibly suck her thumb! Thanks to brain impulses, her facial muscles are getting a workout as his tiny features form one expression after another. Her kidneys are producing urine, which she 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 his thumb.
In other news: Your baby's stretching out. From head to bottom, she measures 3 1/2 inches — — and he weighs 1 1/2 ounces. Her body's growing faster than her 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 h 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.
Baby at 14 wks :)
