Twenty-nine Weeks Pregnant

I am growing rapidly now. This week I weigh about half a pound more than I did last week (about 2 1/2 pounds total) and am a tad over 15 inches long from head to heel. My muscles and lungs are continuing to mature, and my head is getting bigger to accommodate my growing brain — which is busy developing billions of neurons. Every day, about 200 milligrams of calcium is deposited in my skeleton, which is now hardening. With this rapid growth, it's no surprise that my nutritional needs reach their peak during this trimester.
