I've been thinking of you all night Julie, this is such a devastating time for your little family. I think the vast majority of us would wish to go peacefully and in my humble experience, a morpphine driver does make that possible. I believe they only offer this once there is no hope for any recovery, my father's passing from this life was made gentle by it, as was my sister's earlier this year. Given everything you've said I'm hoping that Trevor gets one so that the boys and you (and Trevor) do not have to endure this awful phase any longer than absolutely necessary.
I'm with you in spirit you fantastic wife, mother and human being. As always Lyn gives great advice re James, my daughter is a Teacher and I'm sad to say there is always at least one child having to cope with this every year, they will understand and do what's right for him.
Hugs
