Elsa's contractions have only just started, so they don't go to the hospital straight away. She helps Elsa repack her hospital bag (twice). She makes sure that the nursery is set up with as easy access as possible to everything. Pulls the bottle steriliser out of the box and sets it up in the kitchen while Elsa does her best to relax on the couch.
It doesn't last long. Maybe an hour or two? But then Elsa gets hit with a particularly strong contraction and she starts to panic.
What if something happens to the other baby?
