Baby's Growth and Development at 22 Weeks Pregnant

During your 22nd week of pregnancy, your baby is starting to discover a world around him as his senses continue to develop.

  • When you’re 22 weeks pregnant, your baby is about 7 1/2 to 8 inches long head to rump, around the length of a head of cabbage, and weighs about 1 pound.
  • Your baby's sense of touch and taste progress significantly this week.
    • Taste buds begin forming.
    • Your baby's brain and nerve endings mature enough to process the sensation of touch.
  • Your baby's reproductive system continues to develop. In a boy, his testes begin to descend. In a girl, her ovaries and uterus now are in place and her vagina develops. She already has all of the eggs she'll need for her own reproductive life.
  • When you're 22 weeks pregnant, the surface of your baby's brain, which has previously been smooth, begins to develop folds. This creation of hills and valleys in the brain will continue until the 34th week of pregnancy, when your baby's brain will have enough surface area for a full complement of brain cells.
  • Your baby continues to hear sounds from the outside world. Although these sounds are muffled behind the amniotic fluid and the protective covering of vernix, your baby soon recognizes your voice.
