The Big 3-0
Our baby now weighs about 3 pounds and measures 16.2 inches. Things are started to get cramped inside the uterus at this point, and our 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!
For Mary, sleeping on her left side is probably the most comfortable position now, as it will help remove some of the pressure on the nerves and blood vessels in her back.
