I agree with everything everyone else has mentioned on this thread and would just like to say:
Firstly, don?t go reading up on the internet again. While the internet can be a very useful source of reference, it can also serve to exaserbate any worries you might have, and remember, not everything you read on the internet is from a reliable or confirmed source, so a lot of what you read may not even be accurate. I?d imagine most of us would be dead by now if we went on the internet to diagnose every ache, every pain, every cough and twitch, most of us would probably be convinced we were suffering from a debilitating illness and the stress of us would most likely kill at least some of us.
Secondly, worrying is natural, we all do it at some point. If you are genuinely concerned then I would seak advice from a gp/health visitor. Other than not making eye contact, how does your baby react to visual stimulation? Does he:
Turn his head towards light, i.e. window
React if objects are placed near him i.e. with bright colours
If you come quietly up to him (so he can?t hear you) does he react in any way if you touch him, or does he register that you are there by sight iyswim.
If he fails to do any of these things then I would seak an eye test from an optometrist and/or specialist.
I am totally blind and was diagnosed at 3 months. And I was diagnosed because I failed to react to visual stimulations, but I have light perception so I would turn to look at light from a very early age, but didn?t make eye contact/react to brightly coloured/interesting objects.
I think that you know your baby best and if you are concerned it can?t help to seak the opinion of another, at best they?ll tell you you?re being paranoid, at worst they will confirm your fears and get you further help.
Good luck xx
