blind man in his 40s here. Reduced contact to his overprotective mother. My most important advice: Support your child, but don't forget to let him make his own experiences at some point. Don't overprotect, which is the worst for blind people. Coping mechanisms are very individual, but one pattern is clear: Those overprotected that don't flee from their parents end up being even more disabled. Why? Because you need time and space to figure out what you can do and what you can't do. But parents have this tendency to protect so much that the child can never find out what they are good at. PLEASE, let him grow and and take risks. He will grow by being allowed to take risks. If your wife has over-protective tendencies, speak to her, make her understand. I can not emphasis enough how important that is. In fact, we have a saying in the blind community: "Parents exacerbating the disability" (Zusatzbehinderung Eltern).
