How Tall is Camden?

These pictures are from before Christmas. I was measuring Camden and he had the best time playing with the measuring tape. He has grown 1 inch in the last 3 months. I measured him a couple of days ago and he was 37 1/2inches tall! I read somewhere that at this age you can double a child's height and it roughly tells you how tall they will be when they grow up. That would put Camden around 6'3"!
