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.
