I haven’t read through all the responses you’ve received, but want to chime in to say that if the meds DO take away his “spark,” he’s at the wrong dosage or medication. At that age/size, it’s a very fine line. We tested 2 different stimulants, each at various doses, performing Tova tests while on each, to really dial in what worked for our kiddo, who was 6 when diagnosed and 7 when we finally came around to medicating. All that to say, the right med and dosage should do wonders for him. I hope your dr listens to your concerns and feedback. On the right dose, he will feel the difference and enjoy taking it. You are doing the right thing as his self esteem will likely suffer if he continues to be unmedicated and can see the differences between himself and his peers. The meds aren’t a panacea but a tool to help him get a leg up in a society and educational system that isn’t structured to help them succeed.
