((((((((((((Rain)))))))))))) I think he's just fine. My daughter's motor skills did not advance as quickly as her talking. My son's motor skills were very early and he did not really talk until he was almost 3. My daughter started with one word and added another and another until she was saying sentences. My son hardly said a word and we kept talking to Drs about it and then all of a sudden he started talking and talked in sentences first thing. I guess he was listening and storing up lol. From that point on, he talked from the time his feet hit the floor in the morning until he fell asleep again.

He will learn as he will. At 13 months, I wouldn't worry. Cuddle and read. And enjoy.
