I totally understand what you are going thru. one of my girlfriends DS1 was diagnosed about the same age. He is also very agressive and has no understanding of boundaries. She researched the drugs when he was diagnosed and had to trial a few to get the dosage right. Now he is a different boy, but one day of missing the drugs and he is back to what he was.

You aren't killing your boy by giving him medication to cope with life. you are helping him control himself when he is unable to. I am a high school teacher and it is horrible watching kids with ADHD try to concentrate at school when they haven't had meds. Keepin contact with the dr and let them know what is going on.

Once he has the correct medication you'll find a massive difference in his attention span and his reading and writing will come along in leaps and bounds. My DD1 couldn't read ANYTHING, except her name, when she started school but within 6 months was reading quite well. Don't stress about school until he is there. And it is brilliant he is starting medication before school, as he has a chance to adjust to it before the big change of starting school.

Sounds like you are doing a great job
