Fetal Development at 21 Weeks

At 21 weeks, your baby is about the size of a banana and weighs approximately 12 ounces. The baby’s organs are continuing to develop rapidly, and the baby is becoming more active.

  • Ears: The baby’s ears are fully formed, and the baby can now hear sounds.
  • Limbs: The baby’s arms and legs are growing longer, and the baby is starting to move them more.
  • Skin: The baby’s skin is still thin and translucent, but it is starting to develop a layer of fat.
  • Lanugo: The baby is covered in a fine layer of hair called lanugo. This hair will help to keep the baby warm in the womb.
