My Pregnancy, Week 18

How big is your baby?

Your baby is now around 7 inches long and weighs 5 ½ ounces.

What is happening with your baby?

A protective covering called myelin is beginning to form around his/her nerves. This covering will continue to form up until your baby’s first birthday. If you are having a little girl, her fallopian tubes and uterus have positioned themselves into the correct place. If you are having a little boy, then his genitals may be noticed on your next ultrasound. However, many babies do not like to cooperate during the ultrasound, and the genitals cannot be seen.
