27 weeks!!!!!!

27 Weeks Pregnant

Size = 14 1/2 inches
Weight = 2lbs

You're now 27 weeks pregnant -- this marks the beginning of your third trimester! Congratulations, you are two-thirds of the way there!

This period of pregnancy from 27 weeks onward is known as within the period of fetal viability.

When you are 27 weeks pregnant, 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.
During week 27 of pregnancy, your baby's muscle coordination will allow him or her to start thumb sucking. This activity calms the baby and strengthens cheek and jaw muscles for nursing.
Other fetal development that is occurring when you are 27 weeks pregnant includes the following:
  • The network of nerves to the ear is completed
  • The baby takes some breaths, and although breathing in water, not air, it is good practice for the lungs
  • Eyelids begin to open, and the retinas begin to form
  • Your baby may be able to recognize your voice and your partner's voice.
