39 Weeks

Your baby's waiting to greet the world! He continues to build a layer of fat to help control his body temperature after birth, but it's likely he already measures about 20 inches and weighs a bit over 7 pounds, about the size of a mini-watermelon. (Boys tend to be slightly heavier than girls.) The outer layers of his skin are sloughing off as new skin forms underneath.

Your baby has really plumped up. She weighs about 6.8 pounds and she is over 19 1/2 inches long (about the size of a leek). She has a firm grasp, which you'll soon be able to test when you hold her hand for the first time! Her organs have matured and are ready for life outside the womb.

Wondering what color your baby's eyes will be? You may not be able to tell right away. If she's born with brown eyes, they'll likely stay brown. If she's born with steel gray or dark blue eyes, they may stay gray or blue or turn green, hazel, or brown by the time she's 9 months old. That's because a child's irises (the colored part of the eye) may gain more pigment in the months after she's born, but they usually won't get "lighter" or more blue. (Green, hazel, and brown eyes have more pigment than gray or blue eyes.)
