Week Thirty Three: Lanugo is disappearing

  
You are 33 weeks pregnant. (fetal age 31 weeks)
  • The baby is now 4.4 pounds (2 kg) and around 17.5 inches (44cm) in length.
  • The diameter of the head is about 8.5cm.
  • The baby fuzz, lanugo, is disappearing.
  • Your baby drinks about a pint of amniotic fluid a day.
  • You may gain a pound a week (500g) for the rest of your pregnancy.
  • Half of your weight gain will go directly to your baby.
33 weeksThe baby is using it's lungs to practice breathing by inhaling amniotic fluid. Your baby is drinking about a pint of amniotic fluid a day now and urinating the same amount. The early baby fuzz, lanugo, is disappearing now and being replaced by actual hair. The nails of your baby are now long enough to reach to the tip of the fingers or beyond and may need trimming as soon as they are born. They may scratch their face even before birth.

You may gain a pound a week for the rest of your pregnancy. Do not stop eating or start skipping meals as your weight increases. Both you and your baby need the calories and nutrition you receive from a healthy diet. Calcium intake is extremely important during pregnancy because the baby will draw calcium from the mother to make and harden bone. This can greatly weaken her own bones and teeth because the developing fetus will take minerals from the mother's skeletal structure as needed.
