My baby is 7 weeks old, and we have some concerns about his eyesight. When he was first born we were nervous because he would often bulge both eyes out - looked like he was kind of straining and his eyes were popping out of his head. He has grown out of this, though (although he still has big eyes :) ).
We are slightly concerned because he doesn't often make eye contact - he is always looking all the way up, and often everywhere besides our faces when we're trying to catch his attention. It looks like he's just wandering around and exploring... But often we'll put our faces right up to his and he'll look everywhere else and act as if he doesn't see us. And the same for following movement. He often looks all the way up as if staring at the light (which he likes to do)... even if there's no light there. Note, though - he does occasionally make eye contact or follow a moving object, just not consistently. He also was an early smiler (at about 4 weeks) which I assume means he can see - he always locks eyes and watches us smile before smiling back.
Is there any reason to be concerned or are we overreacting?
