As one of our friends pointed out to me, Elijah is really an observer. He watches other kids and adults for a long time before attempting it himself. For instance, he didn't climb the playground equipment at the park the first several times we went. He contented himself with playing in the rocks and watching other kids. Now he can climb like a monkey. I'm sure this is another aspect where he will talk when he's comfortable with it.
I'll keep everyone updated as Eli starts talking more.
He already has his own cell phone and babbles into it.
Plus he knows how to use Daddy's cell phone too.
