Week 31

Here is BabyCenter's take on week 31:
How your baby's growing:
This week, your baby measures over 16 inches long. Weighs about 3.3 pounds (try carrying four navel oranges) and is heading into a growth spurt. Baby can turn the head from side to side, and arms, legs, and body are beginning to plump out as needed fat accumulates underneath the skin. Baby's probably moving a lot, too, so you may have trouble sleeping because your baby's kicks and somersaults keep you up. Take comfort: All this moving is a sign that your baby is active and healthy.
