aOne of my friends has a 3 month old infant and when I tried to play with him, I noticed he didn t track me when I moved about him. Instead his eyes fluttered almost constantly when I was in his vision range. I tried moving my face and hands further away and it continued. I was trying to see if he would focus and follow the movement of my fingers about 12-18 inches from his face and then a little further. His eyes continued to flutter. He was lying on the floor and when I stood up and moved away he didn t react at all and the fluttering seemed to lesson as I moved away. I don t even know if his mom notices anything. Do you think this is a cause for concern? I have helped raise over 50 children and have never seen this before.
