This week, our baby measures over 16 inches long. He weighs about 3.3 pounds (try carrying four navel oranges) and is heading into a growth spurt. He can turn his head from side to side, and his arms, legs, and body are beginning to plump out as needed fat accumulates underneath his skin. He's probably moving a lot, too, I'm starting to have trouble sleeping because he kicks and somersaults keeping me up. All this moving is a sign that baby is active and healthy.
Our baby's about 15.7 inches long now, and he weighs almost 3 pounds (like a head of cabbage). A pint and a half of amniotic fluid surrounds him, but that volume will decrease as he gets bigger and takes up more room in my uterus. His eyesight continues to develop, though it's not very keen; even after he's born, he'll keep his eyes closed for a good part of the day. When he does open them, he'll respond to changes in light but will have 20/400 vision — which means he can only make out objects a few inches from his face.
Parker now weighs about 2 1/2 pounds (like a butternut squash) and is a tad over 15 inches long from head to heel. His muscles and lungs are continuing to mature, and his head is growing bigger to make room for his developing brain. To meet his increasing nutritional demands, I need plenty of protein, vitamins C, folic acid, and iron. And because his bones are soaking up lots of calcium, I'm needing to drink lots of milk. This trimester, about 250 milligrams of calcium are deposited in his hardening skeleton each day.
