My friend Heather recommended this book/journal to me when I was prego with H. It's called The Pregnancy Journal: A Day-to-Day Guide to a Healthy and Happy Pregnancy by A. Christine Harris. It's an informative way to track and interact with day-to-day changes that take place during pregnancy. It also has tips, advice, cultural facts and space to write about the pregnancy. I'm using my same journal, only writing in a different color ink.
Let's see today, the baby's eyes are now well developed (but not mature enough to do any visual processing). Over the next three days, the tongue will begin to develop. The external ear canal is present. The baby is .62-.71 inches long and weighs about .033 oz - about as heavy as 1/5 teaspoon of water! Even though the baby is surrounded by fluid, it does not drown b/c it does not depend on its lungs for air. Oxygen comes to the baby from you through the umbilical cord blood.
