My MIL has just been diagnosed with terminal pancreatic cancer, my husband and his sister don't want to tell any of the children.
I want to tell mine that granny is dying as they lost there granpa 3yrs ago to kidney cancer and were not told how bad he was and only found out once he died, my eldest in particular took it really badly.
So aibu to want to go against everyones wishes and prepare my children for the worst.
