Week 16

An avocado. From the sonogram Friday we found out that the baby weighs about 4 oz, not the 3 1/2 like the babycenter.com says. :) But I guess babycenter.com says their information is on "general information." See what it says about the 16th week of pregnancy "in general." :)

How your baby's growing:Get ready for a growth spurt. In the next few weeks, your baby will double his weight and add inches to his length. Right now, he's about the size of an avocado: 4 1/2 inches long (head to rump) and 3 1/2 ounces. His legs are much more developed, his head is more erect than it has been, and his eyes have moved closer to the front of his head. His ears are close to their final position, too. The patterning of his scalp has begun, though his locks aren't recognizable yet. He's even started growing toenails. And there's a lot happening inside as well. For example, his heart is now pumping about 25 quarts of blood each day, and this amount will continue to increase as your baby continues to develop.
