Fetal development: The 3rd trimester

Week 38: Baby's toenails grow

Thirty-eight weeks into your pregnancy, or 36 weeks after conception, the circumference of your baby's head and abdomen are about the same.

Your baby's toenails have reached the tips of his or her toes. Your baby has mostly shed all of his or her lanugo.

By now your baby might weigh about 6 1/2 pounds (2,900 grams).
