Organized sports can be more stressful than they’re worth for a kid with ADHD or other behavioral issues. It becomes just more hours in the week that they need to be “on” and well behaved. Activity is great but I wouldn’t push teams. A friend’s son latched on to parkour and is loving it. I can imagine that being easier to find in NYC than baseball as well. It is individual creative action and can be quite feeing and affirming.
