GROWTH FROM FIVE TO NINE WEEKS

Even though you don't look any bigger, your baby is rapidly growing. Check out the ten growth milestones:

1. By the end of the fifth week, baby is the size of a green pea (or about 0.4 inches).
   
2. Pits that become the eyes, ears, nose and mouth begin to show.
   
3. More than one million new cells are added to baby's growing body each minute.
   
4. By six weeks, baby is ½ inch long, and ultrasound can show a fluttering heartbeat of about 140 to 150 beats per minute (twice as fast as yours).
   
5. At seven weeks, baby is around an inch long or the size of a small olive.
   
6. Elbow, wrist and knee joints are obvious.
   
7. Researchers estimate that by seven weeks, one hundred thousand new nerve cells are created every minute.
   
8. At eight weeks, baby is around the size of a large olive at 1½ inches long and ½ ounce in weight.
   
9. All the internal organs that will be present in the fully-grown infant have been formed by eight weeks.
   
10. Developing baby is now called a "fetus" and is beginning to look like a miniature human being.
