Your placenta layers are beginning to thin. Your baby's adrenal glands
are as big as an adolescent's at this stage, but will shrink after birth.
Your placenta is currently converting the hormone that your baby's adrenal
glands are producing to make estrogen.
From head to bottom, your baby is about four pounds, and a little over eleven
inches long! The irises of your baby's eyes are dilating and contracting.
Your baby can react to a bright light as well. The vernix caseosa that is
protecting your baby's skin has become very thick. If your baby was born today,
he or she would have an excellent chance of surviving without any long term
problems.
