As a parent who has made this decision myself, I certainly wasn't "happy to" do it. But it's very clear to me that without medication, my child lacked control over his thoughts and actions, and it was affecting his life - school, friendships, etc. - to a degree that was very frustrating for him. He's happier and more successful now. And, it's not a "lifetime supply" for sure - many kids do grow out of it and stop requiring medication by the time they reach adulthood. Some don't, and they can decide where to go from there.
