Around 36 weeks
I actually didn't with my first...I had an appointment at 36+4 where it was meant to be discussed but it wasn't, similarly to you with my first I saw different midwives. She rebooked for two weeks later but my waters broke before then. 🤷♀️ Honestly, just try and know what you want before you go in. The hospital antenatal classes are fairly good at giving you information to make an informed choice.
There's a form you can fill in on badger notes to inform them and put a record by your name.
I was asked quite early what my preference was (e.g. home/labour ward/serenity suite), I'd say 16 weeks. We confirmed this again at my 28 week and she said we will go in more depth at my next which will be 34 weeks x
34/36 😄
