Just a heads up with some unsolicited advice.
Definitely, as Penny said you need a new practitioner but more so Have someone explain why the meds are necessary. It takes some super good parenting to raise kids with ADHD the meds will help slow them down hopefully enough so they can be taught the correct responses to things. The parent and teachers have the responsibility to teach those responses.
I wouldn’t hold your breath on the teacher if its a public school but you as a parent need to really understand the ADHD mind and not just stick the kids on medication just because they are calmer. You must take advantage of their calmness and explain why they have to turn in their homework or stop falling asleep or disrupt the class.
Those kids of yours are a ball of energy that simply needs to be redirected to something they really enjoy engaging in.
Lots of patience,they can be off the meds in a couple of years in some cases.
