What is going on with your baby during week 12?

Your baby is about 2½ inches (6cm) long and weighs ¼ of an oz. Small amount of hair are beginning to cover baby's body, fingernails and toenails are beginning to grow, and your baby's first permanent tooth buds are forming. The digestive system is able to produce contractions that push food through the bowels. It is also able to absorb sugar. The thyroid gland has started to function and the fetal nervous system is beginning to mature. The amniotic sac which houses your baby contains about 1½ oz of fluid and by the time you deliver, the sac will contain about 3-4 cups of fluid. Your doctor is able to detect baby's heartbeat from now on using a Doppler. Your baby is moving inside your uterus but you probably won't feel it for a while yet.
