When replaying the game or if a player wanted to skip the story altogether and just sample the gameplay (which I think would be very rare).
My personal experience:
I played your game twice. The first time I went as far as the first introduction of the baby. By then the story was taking so long I decided to quit, it didn't hook me to keep investing in it.
The second time I just skipped through dialog (and that's when the skip story would've been extra helpful) so I could actually play the game so I could make a more accurate assessment to rate the game.
