Week 12, 13, 14 – Baby notes



Week 12: Your baby weighs about 14 grams and is about 2 1/2 inches in length. Your baby has reflexes and begins to have activity in the digestive tract. Bile is now being secreted and these types of developments are to prepare the baby for life outside of you. Stem cells, the "mother cells" that reproduce to become heart, brain, liver, bone, blood, nerve, and immune cells, continue to differentiate into cells forming your baby's major organs.

Although your baby's brain continues to grow, its components now have the same structure as when your baby is born. If your OB or Midwife uses a "doppler," you may be able to listen to your baby's heartbeat. This may be the sweetest sound you have ever heard. Most new moms are amazed by how fast the heartbeat is.

Week 13: Your baby weighs about 1 ounce and is about 3 inches in length. Your baby's digestive tract continues to develop as inside the intestines tiny villi (hairs) are forming. These villi will assist in moving the food through your baby's digestive tract. The pancreas has begun producing insulin and within your baby's mouth, all 20 teeth have evolved but of course are not visible. (That would make predicting orthodontist bills way too easy?)

Week 14: Your baby weighs about 2.25 ounces now, and should be about 3-4 inches in length. Your baby's bladder begins functioning and believe it or not, actually begins urinating. In fact, although doctors are not really sure of how or where your baby's urine is produced it is a component of the amniotic fluid and is continuously regenerating itself every 3-4 hours.
