Fetal Development Week by Week – Week 27

You’ve made it to the final trimester now, only 10 weeks to go!  Your baby now weighs about 2 pounds and is about 14 inches long.  They look like a fully formed baby at this point, only smaller and very thin.  Survival, if born now, is around the 85% chance rate.  Baby will go through another growth spurt now and may have predictable periods of sleep now.

The ears are covered the waxy substance called vernix which may muffle the sounds that they hear.  Some experts believe that babies begin to dream at week 28, because the brain is so very active now.  Brain tissue is developing rapidly.

It’s possible to hear the baby’s heartbeat by just placing an ear on your abdomen at this point!  Lungs have developed enough that they could function outside of the womb and the central nervous system is well formed.

Amniotic fluid and the absence of fat on your baby’s body makes their skin appear wrinkly at this time.  Baby will continue to fill out after they are born and begin to gain newborn weight.
