Following objects or people with eyes
Baby at around this time turns head and eyes to look toward light source or moving hands. If you move an object slowly across your baby's field of vision, he will track it with his eyes. Eye movements will still be a bit jerky.
Now Juli's eyesight tracked my movement. As I moved around or between her and the camera, I noticed that Juli followed my movement with her eyes.
Goos, gurgles, and grunts still increased. Her attention span also continued to increase gradually. Her gaze had increased a bit longer that I took the opportunity to talk with her in ASL. She seemed to be more aware.
