For Padme'. If she dies on screen that'll conflict with ROTJ. When Leia clearly states that she remembers her mother. So I doubt we'll see her die on screen.

[Jedi Master Carr]

Do you mean if some time passed from the birth to her death, right? That is possible it is the only other thing that would make sense.
