My 8 yo is currently taking Quillivant. We've tried a couple of different meds and are just getting dialed in on the dosage, but it definitely helps him stay focused during the day. His teacher has reported a noticeable improvement at school.
My 10 old has been. We tried 4 and this one we are trying will be the last one but I can say it seems to be helping a little. Much calmer then before.
My 7 yr old is on medicine. He has been for almost two years. We are still figuring out the right dosage. He has had good success at school with being able to focus.
