Your Baby

The lanugo (that soft covering of hair) is mostly gone now and your baby will continue to gain weight, even up to the last week or two of pregnancy. It doesn't have much room to move in the uterus so movements may begin to slow. At this point, all the organ systems are developed and in place. Your baby is still building a layer of fat to help control body temperature after birth. The last part of development is the maturing of lungs. Your baby is ready to greet the world. He is approximately 20 inches and weighs little over 7 pounds.

This time next year your baby will be 51 Weeks Old!. Can you believe it? Time flies so fast! Be sure you start chronicling these memories now by creating your free pregnancy & baby journal today!
