My grandson has all the Ds. OCD, ADHD. etc. He needs attention. Play with him for an hour and he is a happy camper. Then give him something to do. Legos are great for him. He’s 9 but since he was really young you could hand him a Lego kit and he will work on it til he is done. He has to. lol
Puzzles are also a good one. If you give him a large number puzzle he starts from the inside and works on it til it’s done. lol
His largest obstacle is boredom. If he’s bored he makes everybody’s life miserable.
LOL! Sounds like a human version of a border collie.
Legos are an underrated tool.
Not only are they therapeutic, they are a great role-playing device too.
Oh, and playing Legos when young builds new synaptic pathways in the brain.
I’m pretty sure that if not for Legos in my youth I’d now be a serial killer, or a lawyer.
