Your baby's developed oil and sweat glands are now functioning. Chloe's fingernails, toenails, eyebrows and eyelashes are now fully present and will continue to grow until birth. Chloe can respond to sound and can hear you and those around you. Although we assume that the uterus is a quiet place, the baby has been surrounded by noise for a long time. Things like your heartbeat, digestion, other body functions and external noises are heard by the baby. In fact, you may feel the baby jump at a sudden noise. Chloe is now about 14 inches and weighs a little less than two pounds.
The uterus also allows some light to be seen so your baby is aware of light and dark. Chloe's skin is wrinkled and translucent and may have a reddish color due to the presence of dermal blood vessels. Veins are visible through your baby's skin, although it is quickly changing from transparent to opaque. The following months will see increase in body fat. The lungs continue to mature with the development of air sacs and also begin to secrete surfactant (a substance that will help your baby's lungs expand at birth). At this stage of development the various organs have formed. About 4 out of 10 babies born now may survive (with intensive care services).
The network of nerves in your baby's ears is better developed and more sensitive than before. He may now be able to hear both your voice and your partner's as you chat with each other. He's inhaling and exhaling small amounts of amniotic fluid, which is essential for the development of his lungs. These so-called breathing movements are also good practice for when he's born and takes that first gulp of air. And he's continuing to put on baby fat. He now weighs about a pound and two-thirds and measures 14 inches (an English hothouse cucumber) from head to heel.
