Baby's Growth and Development at 9 Weeks Pregnant

When you're 9 weeks pregnant, your baby's body parts and proportions continue to develop and change quickly:

  • During the 9th week of your pregnancy, your baby grows to about one inch, or about the length of an olive.
  • By your 9th week of pregnancy, your baby's skeleton begins to harden. Hardening of the bones (ossification) begins with the formation of cartilage.
  • Her fingers, toes, knees, and elbows develop.
  • Nipples and hair follicles form.
  • Her intestinal system — pancreas, bile ducts, gallbladder, and anus — forms. Her intestines elongate.
  • Your baby's reproductive organs begin to develop internally when you're 9 weeks pregnant.
  • Muscles develop and your baby may start to move — you may feel her movements in several more weeks.
