How your baby's growing: 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, 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.

How your baby's growing: Your baby has really plumped up. He weighs about 6.8 pounds and he's over 19 1/2 inches long (like a leek). He has a firm grasp, which you'll soon be able to test when you hold his hand for the first time! His 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 he's born with brown eyes, they'll likely stay brown. If he's born with steel gray or dark blue eyes, they may stay gray or blue or turn green, hazel, or brown by the time he'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 he'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.)

How your baby's growing: Congratulations — your baby is full term! This means that if your baby arrives now, his lungs should be fully mature and ready to adjust to life outside the womb, even though your due date is still three weeks away.

Your baby weighs 6 1/3 pounds and measures a bit over 19 inches, head to heel (like a stalk of Swiss chard). Many babies have a full head of hair at birth, with locks from 1/2 inch to 1 1/2 inches long. But don't be surprised if your baby's hair isn't the same color as yours. Dark-haired couples are sometimes thrown for a loop when their children come out as blonds or redheads, and fair-haired couples have been surprised by Elvis look-alikes. And then, of course, some babies sport only peach fuzz.

How your baby's growing: Your baby is still packing on the pounds — at the rate of about an ounce a day. He now weighs almost 6 pounds (like a crenshaw melon) and is more than 18 1/2 inches long. He's shedding most of the downy covering of hair that covered his body as well as the vernix caseosa, the waxy substance that covered and protected his skin during his nine-month amniotic bath. Your baby swallows both of these substances, along with other secretions, resulting in a blackish mixture, called meconium, will form the contents of his first bowel movement.

At the end of this week, your baby will be considered full-term. (Full-term is 37 to 42 weeks; babies born before 37 weeks are pre-term and those born after 42 are post-term.) Most likely he's in a head-down position. But if he isn't, your practitioner may suggest scheduling an "external cephalic version," which is a fancy way of saying he'll try to coax your baby into a head-down position by manipulating him from the outside of your belly.
