height

Click Go and here was the result:

Your boy will likely be 6 ft. 2 in. at age 18.

Young men often continue to grow a little past 18 until they reach 21, but their height at age 18 is very close to their final adult height. This prediction is a "best guess" but it's still just that -- a guess. Based on the formula we used there is a 50 percent chance that your boy's full-grown height will be within 0.8 inches (above or below) of this prediction, and a 90 percent chance that it will be within 2.1 inches.

So given this and the fact that he definitely has some PopPop genes, I would expect that our boy will be taller than both of us. How strange to think that someday he will be taller than me and he won't want to snuggle or even call me mommy. I've been reading too many short stories about being a mom of a boy.
