Thirty- four weeks after your LMP, your baby is perfectly formed. All her proportions are exactly as you would expect them to be at birth. Still, she has some maturing to do and some weight to gain before she is ready to be born.
Your Baby’s Progress
Her organs are now almost fully mature except for her lungs, which are still not completely developed although they are secreting increasing quantities of surfactant, which will keep them from collapsing once she begins to breather air. She can make strong movements that can be felt on the surface of your abdomen. Nearly all of the babies born at this stage survive.
Her skin, nails, and hair
Her skin is now pink rather than red, owning to the deposits of white fat underneath it. Fat deposits build up under her skin in order to provide energy and regulate her body temperature after she is born. The protective vernix caseosa that covers her skin is very thick. Her fingernails reach the ends of her fingers, but her toenails are not yet fully grown. She may have quite a lot of hair n her head.
Her irises can now dilate and contract. They already contract in response to bright light and also to enable her to focus, although she will not need to develop this skill until after she is born. She can close her eyelids, and she has begun to blink.
Some babies assume the head-downward positon about now, but there is still plenty of time- most engage after 36 weeks. Although most babies do turn on their own, she may remain in the breech (bottom down) position until birth.
Her Support System
This month the placental layers may start to thin. To make estrogen, the placenta converts a testosterone like hormone that is produced by your baby’s adrenal glands. By now these glands have reached a size equivalent to those of an adolescent, and every day they produce ten times as much hormone as an adult’s adrenal glands.
They will shrink rapidly after birth. The amniotic sac, or bag of water, contains a large amount of fluid, most of which is the baby’s urine; she can void as much as one pint of urine daily. Excess vernix caseosa, nutrients, and products necessary for lung maturation are also present. The umbilical
