DD10 was a "late" reader. When we decided to go with the public school system, we thought she would be more likely to learn and not be bored in kindergarten if she didn't know how to read. Since she didn't have a strong interest in reading on her own (science and math were more fun), it was relatively easy for us to not do anything that would encourage her to learn to read.

DD started kindergarten at 5 1/2 knowing her name, letter sounds and a few sight words. By age six, she was reading things like recipes on her own. By the end of kindergarten, she was reading 100-200 page chapter books independently and didn't want us to read to her (we were too slow).
