Pregnancy Week by Week

Pregnancy Week by Week: 27 Weeks

When you're 27 weeks pregnant, your baby measures about 9.6 inches, crown to rump, and weighs a little more than 2 pounds.
During this week, your baby's brain embarks on a period of rapid growth. The forebrain grows to cover the rest of the brain, resulting in some important brain development.
By the time you have reached week 27 in your pregnancy, the following changes have taken place in your baby:
  • The network of nerves to the ear is completed
  • Eyelids begin to open, and the retinas begin to form
  • Your baby may be able to recognize your voice and your partner's voice.
When you're 27 weeks pregnant:
  • Your balance and mobility may be changing as you grow larger
  • Stretch marks may become visible as your uterus continues to expand
  • You may find it difficult to take deep breaths.
Caring for a baby is a learned skill, so if you and your partner are first-time parents, you might want to take a childbirthing class, where you will learn about such things as:
  • Options for pain relief during delivery
  • What to expect after delivery
  • Common newborn problems
  • "Babyproofing"
  • Infant CPR.
