Baby's Growth and Development at 17 Weeks Pregnant

Between the 17th week of pregnancy and the 20th week, your baby experiences growth changes.

  • Right now, your baby is about 4 1/2 to 5 1/2 inches long, or about the length of a large orange.
  • Little hiccups continue and you might feel them!
  • When you’re around 17 weeks pregnant, a necessary fat called brown fat develops under your baby's skin. This will help keep her warm after birth. Later in your pregnancy, additional layers of fat develop.
  • Air passages in your baby's lungs finish branching.
  • By your 17th week of pregnancy, your baby's lungs prepare to take in oxygen.
