I understand this is out of the blue but after reading your T-shirt entry (CONGRATULATION !! by the way) with regards to your 2.5 year old I was compelled to reply to you just to agree that you are right about the possibilties for your son are and will be no different to any other people on this planet and with the loving guidence from you and your family things will happen just the same as any other families.
I am speaking from my own family experience as me and my wife have children and my son was diagnosed after been in the world just 6months to be partially sighted !!!! and you know the thoughts that go through your mind of the future ahead with the whys? what fors? and hows!!.
Well my son is now 10 years old and he has exceeded ours, his peers and the trainers of all the 'NORMAL' (whatever that means) sports clubs that he has been involved with (Including SKIING !!!).
YES there are moments and differences but isn't there in all tribes?? Our son is enjoying life just like his peers and at the same rate too so I hope this will help you with your winding road along with the beautiful music of the masterful and HAPPY Tony Memmel (THANKS by the way 1st time listern but NOT the last )
PEACE and LOVE Bbrandt33
And like the courageous Anne Frank said: Think of all the beauty still left around you and be happy.
