Fetal Development Week by Week – Week 30

Your baby now weighs about 3 pounds and measures 16.2 inches.  Things are started to get cramped inside the uterus at this point, and the baby is really in the fetal position – with knees bent and their chin touching the chest.  Soon baby will move into the head down position getting ready for their delivery.

Babies do not usually have 20/20 vision when they are born.  Their eyes are well developed and they are reacting to light, but most children do not have 20/20 vision until they are between seven and nine years old. 

The brain is continuing to grow and make connections between nerve cells.  Baby’s digestive tract is nearly complete now and the lungs are nearly fully developed as well.  Lanugo continues to disappear now and the hair on their little heads is coming in.  Some babies are born with a full head of hair!

Sleeping on your left side is probably the most comfortable position for you now, as it will help remove some of the pressure on the nerves and blood vessels in your back.  It may seem as if everyone has a horror story to tell you now about her labor and birth.  Just remember that every birth is different and don’t feel shy about asking people to keep the stories to themselves if they bother you.  You might also find that complete strangers feel the need to touch your belly – everyone gets excited as the birth of your little one grows closer.
