Tucker came from 2.. 4 pound parents and at 22 weeks he is 5 pounds. He reached 5 pounds at 4 months old, he hasnt gained a pound since. However he hasnt gotten any taller either. He may not be done growing yet, but I do believe he is pretty close to his adult weight, if you would of asked me month ago how big I thought he was going to be , I would told you 8 to 9 pounds, because of his growth pattern then, now because he hasnt grown anything in month. I dont think he will weigh an ounce over 6.
Its hard to tell how big they will actually get.
