27 Weeks

(still an eggplant)

The retina develops its normal layers by the 27th week of gestation. These layers are important in receiving light and light information and transmitting it to the brain for interpretation. Your baby's skin is quite wrinkled from floating in water. It will stay this way until a few weeks after birth as your newborn fills out into a baby. Your baby is about 14.5 inches long, and weighs over two pounds.

Your baby is now sleeping and waking at regular intervals, opening and closing her eyes, and perhaps even sucking her fingers. With more brain tissue developing, your baby's brain is very active now. While her lungs are still immature, they would be capable of functioning — with a lot of medical help — if she were to be born now. Chalk up any tiny rhythmic movements you may be feeling to a case of baby hiccups, which may be common from now on. Each episode usually lasts only a few moments, and they don't bother her, so just relax and enjoy the tickle.
