16 Weeks

We had our 16 week appt this morning.  Baby was moving all over the place while the nurse was trying to find the heartrate.  It took quite a while to get the numbers because the baby was such a little busybody.  She finally got the heartrate.  It ranged between 155-160.  She even saw my stomach moving from the baby.  Too cool!

Get ready for a growth spurt. In the next few weeks, your baby will double his weight and add inches to his length. Right now, he's about the size of an avocado: 4 1/2 inches long (head to rump) and 3 1/2 ounces. His legs are much more developed, his head is more erect than it has been, and his eyes have moved closer to the front of his head. His ears are close to their final position, too. The patterning of his scalp has begun, though his locks aren't recognizable yet. He's even started growing toenails. And there's a lot happening inside as well. For example, his heart is now pumping about 25 quarts of blood each day, and this amount will continue to increase as your baby continues to develop.

Week 15

I missed out on last week's post because my dad had a stroke.  He's doing fine now, but last week was just really hard.  We'll pick up where we left off.

Fine hair called lanugo covers your baby, who now measures about 4.3 to 4.6 inches (10.8 to 11.6cm) from crown to rump and weighs about 2.8 ounces (80g).


Fingernails are well formed and the arms and legs may be seen moving on an ultrasound. Your baby already has his own unique fingerprint pattern!

Your baby can hold his head erect and he can also make faces with his slightly developed facial muscles. Your baby may practice squinting, frowning and opening and closing his mouth.

Your baby's bones have enough calcium deposits to show on an X-ray. If your baby is female, her ovaries will be in place in her pelvis and more than five million ova (some of which may be fertilized to become your own grandchildren in another generation!) have formed.

Week 13

Baby measures about 3.2 to 3.5 inches (7.6 to 8.9cm) from crown to rump and weighs about 0.9 ounces (25g). Your baby is now nourished by the placenta.

The face is developing and the cheeks and the bridge of baby's nose are appearing. The ears are moving from the sides of the neck to higher on the head and the eyes are moving closer together. Your baby's external genitals are now distinct and may be recognized on an ultrasound. Your baby will move away from stimuli near your tummy, such as noise and light.

Your baby's eyebrows have formed and a small amount of hair, called lanugo, has appeared all over the body. Lanugo, which will be shed before birth and replaced with the hairs with which your baby will be born, is thought to have a protective function.

Insulin is present in your baby's pancreas. Some bones may be well outlined. Your baby's thyroid gland, already developed by this week, begins to make hormones.

Baby boys begin to develop the prostate gland at this time and the ovaries of baby girls descend from the abdomen into the pelvis.
