ADHD- no such thing, how did they even come up with it. In my country if a child acts like he has "ADHD" it means that he is a very healthy and active child. Right after we moved here a doctor diognosed ADHD in me,my mom thought he was stupid. At first I thought maybe but it got wierd to things so,I felt silly Dont waist your money,this is all they want. Trust me I know a lot on that. Your child smart and active, be happy for him/her.
Good luck
P.s. if you need a way to calm down your child, for any reason. I can tell you how, without any medicine.
