I agree with Christinefrance. My son and daughter-in-law's baby died in the womb, at a stage where it would have survived if born alive. I felt I could not grieve properly unless I had some details, and wanted to attend the cremation service, but they did not want to talk about it and did not invite anyone to go with them to the funeral. Granash, I suggest you ask your nephew and his wife what help they would like. Sometimes the best thing we can do is keep silent, however difficult that is.
What gives you a warm feeling? 🥰
