I have a 5 year old son and 12 year old daughter. My son had a bump on the back of his head, and wasn't himself ever since. He was not eating, and when he did, he would throw up. He would sleep almost all the time. We took him to regular doctors, but they couldn't find anything wrong. We tried CT scans, MRI's, everything. Then someone mentioned a chiropractor. We haved been going ever since. He fixed the problem.
My daughter was also diagnosed with depression, ODD (opisional defiance disorder), among other things. We tried the meds, didn't seem to do much. Then she went to the chiropractor, for something else. After that, she hasn't needed the meds, and she has been a different person. Better, nicer, and happier.
Try it once, and you will love it.
Good luck!
