Midpoint of Pregnancy: Your Baby in the 20th Week of Pregnancy

Updated on

  • Baby size 16.4 cm
  • Approximate weight 300 g
  • About the size of a banana

By the 20th week of pregnancy, your baby has reached the halfway point and has grown significantly, measuring approximately 25 cm and weighing around 300 grams. The baby is becoming more active and you may feel frequent movements. The baby's senses, including taste and hearing, are well developed, allowing him to hear and respond to sounds from the outside world. The baby's skin is covered by a protective layer of vernix caseosa and fine hair called lanugo. This is a crucial period where the baby continues to develop rapidly, preparing for the second half of the pregnancy.
