37 Weeks

Your baby is now considered full term, even though your due date is still three weeks away. If you go into labor now, his lungs will likely be mature enough to fully adjust to life outside the womb. He 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.
