Deciphering Baby Talk

The growth charts are claiming that babies don't start talking until 18 months or so.  I think they're wrong.  Everett is only 4 months old, and he is talking to me every day.  Now, it isn't English.  It isn't any really any recognized language.  But he is talking.  More importantly, I understand it.  In today's "Dad's Eye View", I interpret my son's words, so the world can be blessed with his wisdom.
