I think Jessica makes a good point - all kids are different and the medication that suits one may not be the best for another.  Whatever drug your child is on though - getting the dosage right is the most important thing, whether it is hydrocortisone, prednisolone or dexamethasone.  It is good to hear that your little girl is progressing well Jessica and that she is obviously receiving appropriate monitoring and treatment (another thing that varies as unfortunately not every child is lucky enough to be under a doctor who is so interested and caring!)
