Kids of blind parents are more developed in certain areas.

A study about the children of blind people has shown that they may have an adaptive advantage over children whose parents can see.
Infants begin learning physical and social cues just days after being born.

Things like eye contact and other people’s reactions to behavior are formative in how a child develops.

Researchers from La Trobe University in Melbourne and the University of London studied five children who had primary caregivers that were blind.

They followed the children’s progress for about four years, and found that when tested, the children frequently scored better on memory and attention tasks compared to children with parents who could see.

Atsushi Senju from the University of London said: "This is a somewhat unexpected finding. It gives us an insight into how children can easily learn new cultures and new technologies so easily. Such a capacity might be fundamental to the way humans adapt to the complex social and cultural environment."

One account of growing up with blind parents mentions a woman who says she is unusually observant because she has to verbally explain everything to her parents.
