That's why I had a hb with my 3rd as it was going to be quick, my Mw trained DH and I what we should do and most importantly said trust my body to do what it wanted. We ended up free birthing as she didnt make it and an ambulance was never suggested or called. This pregnancy the midwife has reassured me she won't miss the birth, she said she is happy for a million false alarms the week leading up to bubs (as that's what I do) she said she was just happy to keep coming for long cups of tea and sleeps on my lounge. But in saying that she is very causal about me just birthing the bub by myself and has never mentioned an ambulance.... I'm having my 'birth' planning meeting in the next few weeks so we'll see if its mentioned then...
