A young mum has been told her 4 year old will not live longer than a year

I have had a young mum that has a 4 year old son whom is very ill. She has been told that he doesnt have much time. The mum come to me to be coached to start looking at the blessings she has with her son now.
I used the Byron Katie judge sheet, and did the CTFAR model. It went really well. we are going to have more sessions. I need support strategies to coach her in this very sad situation? She is grieving now, as she knows how ill he is.
