Blind children must know what things are. Some blind children haven't been to a rectory. Some blind children haven't been in a taxi. Others haven't been in a motor home. Go see things with your children.
Blind children read Braille.
They must have Braille books. I like to read and write Braille. I have an electric Braille writer. It has one-handed extension keys because I have cerebral palsy and my left hand is not strong. I have a Braille Speak and Spell and have learned how to spell lots of new words.
