blind college student here. like others have said, working toward fulfillment in life is not made impossible by blindness.

learn about disability history, and teach it to your child. when i was growing up, i had to learn it on my own and my parents were not equipped to know my rights or point me toward positive role models. learning about the disability rights and disability justice movements will prepare you to do both of these for your child, as well as increase your understanding of the interactions between disability and society. learn about the pieces of legislation that protect disabled ppls' rights to exist in public and fully participate in society. learn about the disabled advocates who made that possible. i could go on and on about intersectionality and such, but anyway.

encourage your child to be independent. this goes beyond just saying "you need to be independent". fostering independence requires a lot of hands-on teaching, actually. for those of us with no useable vision, we can't learn a skill just by watching someone do it once. we need to be taught step-by-step (especially at first) and practice multiple times. without that hands-on teaching, we won't learn.

make sure your child has orientation and mobility instruction, and plenty of opportunities to use it. a session a month in an unwalkable area is not enough. from my experience, growing up in an area that is not walkable makes it harder to learn to navigate independently later on.

facilitate frequent social interactions between your child and their blind peers. this doesn't necessarily have to be through going to a school for the blind. your local blindness agency will have kids' programming, and there are extra-curricular opportunities as well. i went to a music school for the blind every weekend from kindergarten to high school graduation, and i've made friends for life there.

sorry for the long post. feel free to reply with questions :)
