I remember being just like my son.. (6yo)

So hyperactive allll the time. Can’t concentrate in school. And stop making noises. Can’t complete a task. Of course back when I was young they put us on riddlin. (Sp?) I feel so bad for my baby boy. It’s got to be exhausting to feel like this 😢 the last thing o want to do is put him on some medication! I was wondering if anybody has any natural ideas? Iv heard vitamin D or K2...CBD oil even? Anyone have suggestions?? I just want him to be able to relax his mind at will!
