That 12 year old at 105kg is roughly 231.5lbs.  I was 6'2" my senior year of high school, and at the start of our football season, doing air raids, 7 on 7s, camps, etc, I weighed in at a fucking shredded 226lbs. Forum Health did a caliper analysis on us at a power meet just before we went to a camp up at Mount Union, and I was 5.7% bodyfat at the time. Humble brag? Maybe. The point I'm trying to make is this fucking parent has blown their child up to the point that at 12 years old it outweighs a (at the time) high-school athlete who is likely at 18-24" taller than the child, and had set records of which several still stand almost 20 years later.  At current, the child weighs more than 50lbs more than I. For fuck's sake. And it loves to be fat... It's really going to love being on a CPAP for its senior prom. Call the fucking CDC and WHO, stupid is officially contagious.
