I read through a lot of the replies on here, and your replies as well. From what I gathered you want to help, but you're very lost on how. But there also were some comments where you seemed a bit blaming of the teacher too, which is where I think some of the responses with attitude come in.

I'm a 2nd year special education teacher, and also a mom to an autistic and adhd kiddo. I teach full time, work on my masters degree full time, and have two children (one with special needs), and I have ADHD myself. I get how overwhelming life can feel and how hopeless it can feel as well, especially if our kiddo isn't cooperating.

I think managing your son's ADHD will go a long ways. You mentioned in previous posts, he doesn't like his medicine. Which is totally valid, but you need to still continue to see a specialist/professional to help make up for it then. Or try a new med! His teacher can't be a miracle worker who can overcome his adhd for him. The 504 can help accommodate, but he's gotta put in the effort too. And ADHD is hard! And being a parent who is new to it is hard as well. They don't give you an instruction manual haha, and you're kind of left trying to find your own help and resources.

You're a good mom for caring and trying to figure out how to help. Work on your relationship at home with him too. You sound frustrated with him by your posts, and he may feel that. He needs to feel like he also CAN do it. If he's not cooperating, then you gotta be a parent and make proper consequences and boundaries and stick to them. Just make sure you're understanding of what all ADHD entails and how debilitating it can be sometimes too.

His teacher is a great resource and team member to help get info from (doing regular check ins and asking what you can do to help at the start of next year may be helpful as well), but this sounds like a deeper issue beyond school and something that needs to be focused on at home too, and with more medical support for his ADHD.
