Your baby’s a bit more than 15 1/2 inches long now, and he weighs almost 3 pounds. A pint and a half of amniotic fluid surrounds him, but that volume will decrease as he gets bigger and fills out your uterus. His eyes open and close, he’s able to distinguish between light and dark, and he can even follow a light source back and forth. Once he’s born, he’ll keep his eyes closed for a good part of the day. When he does open them, he’ll respond to changes in light but will have a visual acuity of only 20/400 — which means he can only make out objects a few inches from his face. (”Normal” vision in adults is 20/20.)
