20-22 Week Fetus

Weeks 20-22

I am at the halfway mark in my development. I weigh just over a pound and am 12 inches long. My sense of touch keeps improving due to the development of my brain and nerve endings. My senses of taste, smell, hearing, and sight are also developing. My skin is thickening and I am putting on weight. This will help me keep warm after I am born.

I am awake more often. You can watch me on the ultrasound stroking my face, sucking my thumb or playing with my umbilical cord. I am in continual motion, kicking, rolling over, and doing somersaults.

If I am sleeping I might wake up when mommy taps on me.
