Ren I didn't think to check out hospital policy. Is that something you knew beforehand or not until it was happening?
Funnily enough it came up when I was checking with- with the midwife I ended up birthing with! She told me about the 2 hour limit then when I was asking about reasons for transfer out of the birthing centre. I argued it then saying 'what if I am okay with going for longer than 2 hours?'. The impression I had throughout my pregnancy though was that women rarely take longer than 2 hours and you'd be so buggered by then if you had that intervention would be pretty much necessary.
I was concerned about a few hospital policies and freaked out that I wasn't having a homebirth quite a few times... in the end my labour went well but I bet I wouldn't have torn if I'd birthed at home.
