37 weeks

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