When the child visits the chiropractor he gets his spine checked and re-aligned, well Dr. Cyrus explained to me it naturally post the body's immunity system. No drugs no medication and actually it help with many health issues in children.
Go to their website maybe it will help

My son likes the stickers he gets from Dr. Cyrus after his spinal checkup.
Good luck
