Many thanks to you and your grandson for doing this study. I am anxiously waiting to hear the results. Our 23month old daughter has been on dex. since birth. She is doing very well and I feel good knowing that dex is long acting therefore protecting her longer. That being said,I do wonder wether or not the dex. is cotributing to her very tiny appetite. Her levels have always been good. Please let me know if the dex. decreases his appetite.
