Continuing Development: Your Baby in the Eighteenth Week of Pregnancy

Updated on

  • Baby size 14.2 cm
  • Approximate weight 190 g
  • About the size of a bell pepper

In the eighteenth week of pregnancy, your baby has grown noticeably and measures approximately 14-16 cm and weighs around 200 grams. Your baby's movements are more coordinated and you may feel stronger and more frequent kicks. The structures of the face are well defined and the fingerprints are fully formed. The ears are in their final position and the baby can begin to hear sounds, including your heartbeat and your voice. This is a fascinating period where the baby continues to develop and prepare for the outside world.
