Good for you! I'm so glad to hear that you're doing this and I'm sure you'll be happy you did. Your child will not only be happier and more productive and balanced, but will some day thank you for it.
The drugs ("medication") kids are receiving are very damaging and are known for causing psychotic episodes in adulthood, not to mention drug addiction.
A whole, balanced diet free of chemicals can do wonders. I've seen it for myself. There are also herbs that can do wonders along with that, but you'll have to be careful and do your homework. Also, believe it or not, flower essence can make a huge difference too. But of course you have to find the right one for her and be consistent for at least a year. Check into the Bach remedies.
Keep up the good work and know you're not the only one working to do the right thing and lifting your child to a place of deep respect by giving her what will bring out her best and honoring her body, mind, soul and spirit. Kudos!
