Week 27

Your Baby's Development

By this first week of the third trimester, your baby looks similar to what he or she will look like at birth, just thinner and smaller. The lungs, liver, and immune system still need to fully mature, but if born now, your baby would have a very good chance of surviving.

As hearing continues to develop, your baby may start to recognize your voice as well as your partner's. Sounds may be muffled, though, because the ears are still covered with vernix, the thick waxy coating that protects the skin from becoming chapped by the amniotic fluid.

Your Body

Your body continues to protect and nourish your baby. But what happens when it's time to meet your little one? Consider signing up for childbirth classes through your local community center or hospital to learn about labor, options for pain relief, and what to expect after delivery. You'll also learn about common newborn problems, babyproofing, breastfeeding and formula feeding, and infant CPR. Learning all you can about birth and babies will help you feel more confident, especially if you're a first-time parent.
