I heard stories of people speaking VERY late. By some accounts, Einstien didn't speak until he was FOUR! The average child speaks with about 50% clarity by 2! BTW if he LEADS you to what he wants, then he clear knew, decided, figured out how to lead you, and acted on it. So you have to wonder WHY he isn't speaking. Maybe if you asked him to speak, and were less willing to move, he would talk.
