He will get as big as he gets. I don't think there is anyway to tell for sure. He may stop growing soon, or maybe just keep growing and grown. My Charlie just kept growing and he's not just over 13 lbs. But I still love him the same. He's still my baby and I wouldn't trade him for anything. Don't stress on it too much. I know I did, but in the end I seen it's all good.
