I scored this at the thrift store on Saturday! I didn't even want to go but Dan made me, good thing I did.
Week 14
This week's big developments: Your baby can now squint, frown, grimace, pee, and possibly suck its thumb! Thanks to brain impulses, facial muscles are getting a workout as tiny features form one expression after another. Kidneys are producing urine, which the baby releases into the amniotic fluid around it — a process it'll keep up until birth. Your baby can grasp, too, and if you're having an ultrasound now, you may even catch it sucking it's thumb.
In other news: Your baby's stretching out. From head to bottom, it measures 3 1/2 inches — about the size of a lemon — and weighs 1 1/2 ounces. Its body's growing faster than its head, which now sits upon a more distinct neck. By the end of this week, arms will have grown to a length that's in proportion to the rest of the body. (legs still have some lengthening to do.) It's starting to develop an ultra-fine, downy covering of hair, called lanugo, all over the body. Your baby's liver starts making bile this week — a sign that it's doing its job right — and the spleen starts helping in the production of red blood cells. Though you can't feel the 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.
