The average size of the baby at week 22 of pregnancy baby development is around 11 to 12 inches, right about the size of a full grown squash or a red bell pepper. The baby will continue to practice sucking and grasping, and will grasp for the umbilical cord.
According to perinatologist Mark A. Curran, babies born at week 22 of pregnancy baby development have a 9% chance of survival. At this stage, the lungs are not yet fully developed. Lungs will mature around week 34 to 35.
Your baby is swimming and snug inside the fully formed placenta at 22 weeks of gestational age. The neural brain parts like hippocampic fissures and callosal sulcus will already be there according to the University of New South Wales embryology timeline. The spleen and cerebrum also take center stage in baby’s development at this point in time. These are all critical to the baby’s overall brain development and protection as well as the central nervous system. The sleep cycle of your baby is also beginning to develop this week in his or her development and can respond more sensitively to light and dark.
By this time, you can also know the gender of your baby if you want to during an ultrasound. All this with the baby’s stronger grip and better eyesight is getting the baby closer and closer to full human maturity.
The most exciting part is that your baby can already hear you clearly at this stage. From the food you are digesting to the words you say to the world around you, this is already beginning to make an impression on your little bub’s life.
