How old is your son? If he isn’t aggressive and learns how to read, write and do a little math then medication is probably not needed at this time. But do keep a close eye on it because ADHD can cause very serious emotional distress on a daily basis, espesially if he doesn’t understand it. It’s good to be a sceptic and not immediately ho for medication but I can say that god I wish I was diagnosed and medicated at least 15 years ago already, and not at 32.
