We taught our own children to read. But more importantly, to love reading! If your son or daughter needs help with reading - even at special needs levels - start to read book TO them that they love and enjoy! even as a bedtime routine, this is a huge help in developing the part of the brain used in reading and understanding language. Pick books they love and will ask questions about, hopefully ones that are written well, but are fun and engaging. "The Lion, the Witch, and the Wardrobe" is a great place to start, or Dr Seuss books, which help develop sound and language skills.
Another trick for the brain is to forget the names of the letters, and start using he sounds of the letters... instead of saying "em" for the letter M, you say "mmm" - instead saying "A: you say "Aah". There is a great Sesame Street video where Big Bird sounds out the whole alphabet in one word. It's great!
hope this all helps!
