Who is 5 feet 6 inches tall and 122 pounds? My just-turned-12-year-old child. He is 1 inch shorter and 12 pounds lighter than me. If he follows the same fast track he’s been on since birth, he should be about 6 feet 5 (give or take an inch) as a full-grown dude. That sorta scares me. It also kinda thrills me that I get to see this kid almost pass me by because when he was 3, and I had breast cancer, I wasn’t sure I’d see it happen.
