What Lil Arroyo is Doing Now...

Week 26 is here!  Can you believe it!  Boy am I tired, which means he must be growing like crazy and hopefully that means he is nothing but healthy!  Here's what's going on with him now:

The network of nerves in our baby's ears is better developed and more sensitive than before, in fact his hearing system is now completely formed.  He may now be able to hear both my voice and Roberto's as we chat with each other. He's inhaling and exhaling small amounts of amniotic fluid, which is essential for the development of his lungs. The air sacs of the lungs, called alveoli, will be developed by the end of this week and will begin to secrete a substance called surfactant that keeps the lung tissue from sticking together. These so-called breathing movements are also good practice for when he's born and takes that first gulp of air. And he's continuing to put on baby fat.

His eyes are almost fully formed. Did you know that all babies have blue eyes in the womb, no matter what their genetic inheritance is? A baby's eyes don't get their final color until a few months after they are born. The air sacs of the lungs, called alveoli, will be developed by the end of this week and will begin to secrete a substance called surfactant that keeps the lung tissue from sticking together.
