My youngest daughter never uttered a syllable until she was three and a half. Twice a month my wife took her to a special clinic in Tokyo. She started a pre-kindergarten class as soon as she turned 3 and either the class, or the clinic did the trick. One month ago (aged four and a half), the clinic said she no longer needed to go.
If it makes you feel any better, did you know that Einstein couldn't speak until he was 8?
