Three times in the last couple of months my 13 year old son has been asked if he's got ADHD. Once was at Go ape in the summer holidays when he was fiddling with a strap whilst in a queue, once when he was tapping on a desk at school. He's a perfectly normal 13 year old boy, very active, full of hormones, typical teenage emotion swings and like a most boys of that age can be a dickhead at times.
Also a school nurse when they went for a vaccine recently said he was "dangerously skinny" and started asking him what he eats in a day FFS!! He is short for his age and lean but perfectly in proportion. Hes very, very fit, eats like a healthy diet and like a horse, plays football or fustal 4 times a week, does crossfit twice a week and when hes not doing that he's out on his mountain bike.
I find it absolutely ridiculous that people are asking young kids if they have a mental condition for doing what normal teenage boys do or telling them they're too skinny when so many kids these days are too fat and sit on their arse playing computer games.
