AIBU and PFB? Need a reality check here ... 
PFB is almost 4, and at nursery they have decided to have a "film" day later in the week when all of the children watch a film together. I asked what films, they said maybe the Lion King.
Before I could think it through, I asked them not to show the middle section where Mufasa dies. While PFB loves the Lion King, I made the decision not to show that section about a year ago after PFB got very very upset about the idea of me or DH dying, and parental mortality in films (Nemo, Frozen etc) does really affect them. Death is something I get a lot of questions about, and PFB has had nightmares about. I don't want that part of the film shown in a situation where I can't be there to explain it.
I know now I should just watch the whole thing with PFB beside me to explain it, but don't have time before film day.
Am I being terribly PFB? It all just came out to the nursery teacher, and I walked away feeling like that parent ..
