My 8.5 yr old is ADHD and I am as well.
I had the problems you are talking about. Is she on medication? That's the only thing that has helped myself and my daughter. We do vitamin supplements and medication. Magnesium, Flaxseed oil , B vitamins, vitamin C and a small can of coke zero ( none of the sugar but all of the caffeine) in the morning because mornings are AWFUL before her meds kick in.
We also tried everything.
Also pick up the book " Taking Charge of ADHD" by Barkley.
And pick up " learning to slowdown and pay attention. " I don't remember the author but it's a book written for kids with ADHD.
