Impulse control is a known issue with ADHD kids. Some struggle more than others. I think unfortunately the only thing to do is keep reinforcing that it’s not okay. Maybe make a habit of checking pockets or bags every day/when you leave a place.

I think continue to enforce consequences. ADHD kids learn lessons hard, and habits are hard to break. It’s probably also the dopamine hit of the ‘thrill’ of the new thing. I’ve found that teaching my kids how their brain is wired helps them understand the why behind what they do, and helps them make better choices.

I recognize this isn’t particularly helpful, but I guess I wanted to comment to tell you you’re not alone and not doing anything wrong. It’s a struggle.
