Fetal Development - Week 12 (Video)

Your baby weighs about 14 grams (0.5 ounce) and is just over 2 inches in length (crown to rump). His or her reflexes are functioning, and the digestive tract is active and secreting bile - all to prepare your baby for life outside of your body.
Stem cells, the "mother cells" that will become heart, brain, liver, bone, blood, nerve, and immune cells, continue to differentiate to form your baby's major organs.
And although your baby's brain continues to grow, the components now have the same structure they will have at birth. If your OB or midwife uses a fetal Doppler, you may be able to listen to your baby's heartbeat - perhaps the sweetest sound you've ever heard.
