Even though I don’t look it yet, our new baby is 15 and a half weeks.

So I found ten interesting facts online about the fifteenth week of pregnancy. I also found out the stuffy nose I have could be a side effect of pregnancy, though I doubt it since Tyler and Gem both have stuffy noses and I am pretty sure they aren’t pregnant.

By the way, if any of this list is untrue, I apologize; I just copied and pasted off of various baby websites.

1. The baby now measures about 4 inches long, crown to rump, and weighs in at about 2 1/2 ounces (about the size of an apple).

2. The baby can move all joints and limbs. The baby’s legs have grown longer than the arms and the body is now longer than the head.

3. Although the eyelids are still fused shut, the baby can sense light. If you shine a flashlight at your tummy, for instance, it will likely move away from the beam. (Who finds out this stuff? How many ultrasounds do they do while pointing a flashlight at the baby?)

4. There’s not much for your baby to taste at this point, but taste buds are forming. And the baby can develop hiccups from time to time.

5. The baby might start sucking his thumb this week. (How could you possibly know that? Are there ultrasounds of thumb sucking babies?)

6. This week, the baby will start producing lanugo, which is fine hair that will cover the baby’s body up until a few weeks before birth.

7. The baby is spending most of its spare time practicing breathing, by inhaling and exhaling amniotic fluid. Believe it or not, the very act of doing so will help the baby’s air sacs develop during pregnancy. (I guess if you’ve got nothing else to do, you might as well practice breathing.)

8. Baby’s major organs are now fully ready.

9. The baby can hear you and other sounds.

10. The skin is very thin and blood vessels are visible.
