See what's happening with your baby in the eighth month of your pregnancy.
Week 31
Will it be baby blues or a brown-eye girl? Your baby's iris color begins to appear around the thirty-first week. Most babies are born with dark blueish-brown or bluish-gray eyes, but this shade almost always changes after birth. True eye color won't be apparent for six to nine months -- final formation of eye pigmentation happens in response to exposure to the strong light of the outside world.
In the meantime, the fetus's eyes are being readied for life after birth. Pupils begin to dilate in response to the soft, pinkish-red light that filters into the uterus. Eyes are usually open during alert times and closed during sleep.
