31 Weeks...

Your babies each weigh approximately 3.5 pounds, measure just over 16 inches from head to heel, and are getting used to the world of light and dark by opening and closing their eyes. Their facial muscles continue to strengthen, and they can make different expressions. Their lungs are nearly mature; however, these last few weeks are crucial to healthy and complete lung development.





*The rate of physical growth slows down just a bit, but even though she doesn't get much longer, she will gain a lot of weight the rest of the pregnancy.
*Fat continues accumulating. This layer of fat turns her skin from red to the rosy pink she will have as a newborn.
*Calcium, phosphorus and iron are being stored and her bones are growing and hardening.
*Your baby is 16.2 inches (41.1cm) long and weighs 3.3 pounds (1502gm).
*Her brain enters another period of rapid growth, producing hundreds of billions of new nerve cells! Amazing!
*She may move to the rhythm of music. Studies with heart rates show that she also prefers some types of music to others -- already!
*Lungs are the only major organ left to complete development. Remember, that while you may be anxious to meet your little one that these last few weeks can be vital - with each day increasing your baby's ability to breathe on her own.
