C.O.
Welcome to your life with commentary. My son is the same way, and has been just like yours--since he could start making sounds it hasn't stopped. At 18 months he seriously can say over 100 words and is starting to string them together. Encourage it!! at 11 months he is starting to really put it all together in if you really start to focus in on a couple of specific words at a time now, he can start to understand basic things like More and Bottle and Water, etc. (you can even start to teach please--its not too early!!) Then it just gets easier to communicate and less frustrating for him.
Also--consider the source. I do not ever shut up. I am in sales and could seriously talk all day and all night. I expect my kids will be the same way!!
