18 Weeks: My Baby Begins to Hear

Today marks the 18th Week of my pregnancy.

  • The fetus is now 6 inches long and weighs 7 ounces.
  • The fetus measures about 15cm and weighs almost 200 grams.
  • They can hear sounds and may be startled by loud noises.
  • Recognizable active and rest periods.
  • The skin is building a protective wax layer (vernix).
Vernix (a white cheese like protective material) forms on baby's skin with the lanugo, a soft lightly pigmented hair covering the body and limbs, both help to protect my baby's skin during the months in water. My baby may hear my heart beating, my stomach rumbling or blood moving through the umbilical cord. He or she may even be startled by loud noises.

Tiny air sacs called alveoli begin to form in lungs and the vocal chords are formed. Baby goes through the motions of crying but without air doesn't make a sound; yet

My baby may have the same awake and sleep patterns of a newborn. Baby will have a favorite position for sleep and recognizable active and rest periods.

My baby measures about 6 inches (15cm) crown to rump and weighs 7 ounces  or about 200gm.

I will visit the maternity clinic tomorrow for my 3rd pre-natal check-up... Hope that everything will be fine. I am so thankful that after a quite difficult stage (that is, during the first trimester), I haven't felt anything unusual.
