40 Weeks Pregnant

Week 40
Return to Fetal Development Overview

  • At 40 weeks pregnant, much of the vernix has vanished but you will notice traces on her body.
  • 15% of your child's body is fat. Since he hasn't learned to shiver yet, these fat stores will help regulate his temperature.
  • Approximately 60 - 75 percent is water!
  • Your baby's chest sticks out, almost as if he's ready to strut proudly over his accomplishment!
  • His lungs will continue developing until birth. They are manufacturing large quantities of surfactant which works to keep the air sacs open.
  • She continues to grow; her hair and nails longer as well. You may need to trim those fingernails soon after birth or protect her face from scratches with mittens.
  • Small breast buds are present on both sexes at week 40 of pregnancy.
  • The baby now weighs 7.6 pounds (3462gm) and is 20.2 inches (51.2cm) long.
  • Congratulations! Any day now you will be cradling your son or daughter! Cherish the moments and learn all you can about this new personality in your life. They go by all too fast!
