That's my nephew in the picture below. He is a joy to be around. So hppy and giggly. He's always babbling about something, or "telling stories." But, he kind of worries me. I don't know much about child development, so maybe there's nothing to worry about, but he's 2 1/2 and hasn't started talking at all. He will just make noises or grunt. Is this normal? My other nephew was talking by the time he was just over one year old.
