- At 20 weeks pregnant, 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 in week 20 of your pregnancy. She has approximately six million eggs in her ovaries. About one million will remain at birth.
- After 20 weeks of pregnancy, your baby is about 6.46 inches (16.4cm) and weighs around 10.58 ounces (300g).
