baby: "I'm still tiny. In fact, I'm only about 3 inches long crown to rump — roughly the size of a jumbo shrimp — and weigh just about an ounce. Despite my small proportions, I'm a fully formed baby now. Much more proportional than I was a few weeks ago, my head is now only about a third the size of my body. My tiny, unique fingerprints are already in place. My kidneys and urinary tract are functional."
