20 Weeks - Half Way There!

How your baby's growing:Your baby weighs about 10 1/2 ounces now. She's also around 6 1/2 inches long from head to bottom, and about 10 inches from head to heel. (For the first 20 weeks, we use measurements taken from the top of the baby's head to her bottom — known as the "crown to rump" measurement. After that, we use measurements from head to toe. This is because a baby's legs are curled up against her torso during the first half of pregnancy and are very hard to measure.)A greasy white substance called vernix caseosa coats her entire body to protect her skin during its long submersion in amniotic fluid. (This slick coating also eases the journey down the birth canal.)Your baby is swallowing more, which is good practice for her digestive system. She's also producing meconium, a black, sticky substance that's the result of cell loss, digestive secretion, and swallowed amniotic fluid. This meconium will accumulate in her bowels, and you'll see it in her first messy diaper (although a few babies pass it in utero or during delivery).Note: Every baby develops a little differently — even in the womb. Our information is designed to give you a general idea of your baby's development.

You're half way there!
The rapid growth stage is about over. While things have slowed down, this next stage is vital to survival.
The baby's heart grows stronger. Find a quiet place, lay flat on your back. Locate your own heartbeat by finding your pulse. Next lay your hand on your belly. You may be able to distinguish the two heartbeats!
His legs are reaching their relative size. With the increase muscle develop occurring as well, you will start feeling much more than tiny flutter kicks soon!
Immunities are being transferred from you to your baby now. These immune cells will protect her from viruses you've already had for up to six months after birth!
The nerve cells for taste, smell, hearing, seeing, and touch are now developing in specialized areas of the brain. Production slows down as existing nerve cells grow larger and make more complex connections.
Your baby may startle in reaction to loud sounds. Amazingly, she can actually hear noises outside of the womb. Familiar voices, music, and sounds that baby becomes accustomed to during her development stages often are calming after birth.
If your baby is a girl, her uterus is starting to develop. She has approximately six million eggs in her ovaries. About one million will remain at birth.
Baby is about 6.46 inches (16.4cm) and weighs around 10.58 ounces (300g).
