I'm searching for a research-backed answer to a question about introducing children to difficult emotions in movies.
There a seemingly innocent titles like Lion King, Bambi, or Finding Nemo which, while being otherwise colorful and cheerful, contain very sad scenes (in particular, all three movies depict the death of a parent in one of the first scenes!).
I know there might be no single good answer suitable to children of all ages, cultures, and all levels of development, but I'd like to know is it better to fast forward/skip these scenes, or watch and discuss them with my kid. I'm expecting rules like "you shouldn't do that until a kid has ability X" or "you should do that if ...".
So far I've found a 2014 article by Andrea Nair for ymc which suggests that kid below 2 years old, should not watch any screen at all, and that the reason story tellers include these scenes in the first place was not to introduce these topics to children but rather to construct a plot in which a child is on its own adventure (which sounds like a rather not-well-thought-out decision).
