I offer my deepest sympathies and condolences. It is heartbreaking when we loose someone we've loved and cared for. You gave that little girl more time on earth to love and be loved than she would have had if you hadn't come along. She came into this world with so many challenges. Your love made her spirit whole even though her body could not be made whole.
Each day she was alive and happy on earth was a little miracle , itself.
You and your family are in my thoughts and prayers.
