Tall Boy Growing

We finally got around to me-asure Bjorn and he is now approx. 28.5 inches tall (28.5 inch = 72.39 centimeter), which I think is pretty tall for a boy his age (7 1/2 months), so far it seems that he is growing approx 1/2-1" every month, so if that continues, he will be around 32.5-33 inches tall by the time he is one years old (82.55 cm tall). I wonder if he is going to be really tall or average (an again, American average vs. Swedish average), most men in my family are around 6 - 6.2 feet tall(179-183 cm), but my great-grandfather was taller (I don't recall how much taller), so we'll see when Bjorn is 20-22 how tall he has become : - )
