I have two 8 years old boys with ADHD and one time, their pediatrician told me to try to give them coffee or tea before school, but I'm afraid to try that because I don't know if the caffeine will actually work or make them extra hyper.
I have ADHD as well but I got better as an adult. Now, when I drink a strong coffee or coke I get sleepy, but at the same time kind of jumpy.
I have a friend that also has ADHD, now he is a physician and he doesn't believe that kids should be on medications for this condition because he never toke any kind of medication for ADHD and he got also better. He also advice me about the caffeine.
PS: My boys are not medicated.
