From Babycenter.com: "The most dramatic development this week: reflexes. Your baby's fingers will soon begin to open and close, his toes will curl, his eye muscles will clench, and his mouth will make sucking movements. In fact, if you prod your abdomen, your baby will squirm in response, although you won't be able to feel it. His intestines, which have grown so fast that they protrude into the umbilical cord, will start to move into his abdominal cavity about now, and his kidneys will begin excreting urine into his bladder.

Meanwhile, nerve cells are multiplying rapidly, and in your baby's brain, synapses are forming furiously. His face looks unquestionably human: His eyes have moved from the sides to the front of his head, and his ears are right where they should be. From crown to rump, your baby-to-be is just over 2 inches long and weighs half an ounce."

I went on Google to try to find what weighs half an ounce. Don't do this! You will quickly learn how much money you need to buy an ounce of marijuana. I'd like to refrain from comparing our baby to anything called "weed." :0) It turns out that half an ounce is 14.1745 grams. A dollar bill weighs 1 gram...so pull out 14 dollar bills (it doesn't matter what the bill actually is but if you have 14 twenties hanging around I will willingly take them off your hands!) I am guessing that 14 bills equals just under what the baby weighs.
