Second Trimester: The Baby at 24 Weeks
  • Bone marrow begins to make blood cells.
  • Taste buds form on your baby's tongue.
  • Footprints and fingerprints have formed.
  • Real hair begins to grow on your baby's head.
  • The lungs are formed, but do not work.
  • The hand and startle reflex develop.
  • Your baby sleeps and wakes regularly.
  • If your baby is a boy, his testicles begin to move from the abdomen into the scrotum. If your baby is a girl, her uterus and ovaries are in place, and a lifetime supply of eggs have formed in the ovaries.
  • Your baby stores fat and has gained quite a bit of weight. Now at about 12 inches long, your baby weighs about 1½ pounds.
