Looking for some advice on induction for a birth partner!

My darling sister is currently 41+5 with her second bubba - her DD arrived naturally after spontaneous labour starting at 41+1 and we were all sure that #2 would arrive in his own time... but the dreaded 42wks is looming and she has been booked for induction on Friday morning, when she will be 42wks.

She's a bit nervous about being induced and I thought I'd do some research for her on what she needs to know so I can be a good birth partner and help her stay empowered and in control.

From what she has said, the plan is:
- second stretch and sweep Thursday (she had one Monday)
- back Friday morning (if nothing has changed overnight) when they will do an AROM
- I believe they are happy to let her walk around and spend a bit of time trying to start labour naturally from this point but...
- ... at some stage after this (not sure how long they will give her) they will hook her up to the drip if labour hasn't started

I've picked up the following from other threads:
- Try and get her as much time as possible after AROM to start things spontaneously
- If drip is required, start on as low a dose as possible
- If ctxs start on low dose, ask if drip can be removed to see if labour continues on its own
- If drip increase is required, increase slowly to allow her time to adjust

What else do I need to know??
