Baby's Growth and Development at 16 Weeks Pregnant

During your 16th week of pregnancy, the muscles throughout your baby's body are beginning to work.

Ultrasounds can capture your baby's basic movements as early as the 8th week of your pregnancy! Your doctor might schedule one for you between the 16th week of pregnancy and the 20th week.
  • Your baby is about 4 to 5 inches long — about the length of a large pear.
  • Your baby's skeletal and nervous systems connect enough to allow him to coordinate movement.
  • When you're 16 weeks pregnant, developed facial muscles make it possible for your baby to squint, frown, or try other facial expressions.
  • As back muscles strengthen, your baby is able to straighten his posture a little.
  • Your baby now has eyelashes.
  • By your 16th week of pregnancy, your baby's eyes move side-to-side and even perceive some light, although his eyelids are still sealed.
  • Your baby's bones build and strengthen with the help of your body's calcium!
  • Your baby already might be having tiny hiccups, although when you’re 16 weeks pregnant, your baby is not large enough for you to feel them yet!
  • Having a girl? Within your baby's tiny ovaries, millions of eggs already are forming, giving her the chance one day to have babies of her own!
