Helping a Dying Parent

What do I have to do to help in the dying process of my father. I mix massage oil with some drops of essential rose oil and massage his head, forehead, hands and feet. I do it sometimes praying others in such a caring way that he sleeps like a baby. Sometimes I feel that he is getting out of his sickness (getting better) and sometimes I feel that he is getting in peace with himself. Please tell me if am I doing what I have to do? Should I bring him flowers and play him music?
