Weekly Fetus Update and Winners!

Update from The Fetus:
Today marks 17 weeks of Mommy's pregnancy! I'm getting so big, and Mommy is starting to get excited for her ultrasound next week. I also think she's starting to feel me at night sometimes. She woke up one night this past week around 4am and could feel me moving and grooving. Whoops...didn't mean to wake you, Mommy! Here's what's going on this week...
  • By the end of this week I will weigh about 5.25 ounces (150g) and measure 5 to 5.6 inches (12.5 to 14cm) from crown to rump.
  • I am practicing breathing by gulping amniotic fluid into my lungs. This helps my lungs' development so they will function at birth.
  • I may also be sucking my thumb!
  • Meconium is present in my bowels. (ew)
  • There is hair present on my scalp and sweat glands are developing.
  • I am becoming more sensitive to the outside world and am moving around, kicking and punching. Since there is still plenty of space in Mommy's uterus, I can move around a lot, sitting cross-legged, reclining or even turning somersaults!
  • I can probably hear by now as the ossicles (the bones that pass sound to the inner ear) have hardened and the portion of the brain that receives signals from the brain is under development.
  • I am getting used to the sounds of Mommy's heartbeat and blood passing through the umbilical cord, but I may be startled by loud noises.
  • I am aware of some things in the outside world, including sounds and light. If Mommy were to let the sun shine on her belly, I might be able to perceive a warm red glow.
  • Fat is beginning to form on my body and will continue to do so until I am born.
  • My placenta is continuing to grow at an amazing rate. It will continue to develop right along with me, and it will weigh more than a pound when I am born! By this week, my placenta is large and well established with a network of blood vessels that exchange nutrients and waste.
  • My umbilical cord is also growing stronger and thicker.
  • My skeleton is changing from soft cartilage to bone.
  • A protective coating called myelin is slowly beginning to cover my spinal cord. This coating will help protect the cord for the rest of my life.

I love reading about fetal development! It's such an amazing thing. And I love the picture you included, too. I know a lot of people think they look like aliens, but I think fetuses are cute!
