Statistically home born is safer for women who are full term with an uncomplicated pregnancy,...lots of research out there to back this up.
In this case however, the baby is breech and most midwives and doctors never come across vaginal breech births now. Most can only deliver with the aid of theory behind them and no actual experience. The exception I. Elusive is a midwife named Mary Cronk who is probably now retired. She was hugely experienced in breech births and home deliveries, however she had a very strict criteria she adhered to and Mum was transferred to hospital if labour deviated from the progress expected for a baby in a breech presentation.
As an ex community midwife I would also say that lots of women book home births for a first baby but many when faced with the reality of labour decide to go in. Equally many do not and I have helped many women birth their babies safely at home. I would never have felt qualified to assist with a breech presentation though, my only experience was with a woman who had a rapid labour at home, wasn't going to make the hospital and whose baby arrived bottom first with ease.
From my experience there will be lots of stuff going on behind the scenes, a sensible plan of action for labour that they will ask this Mum to think about and agree to. At the end of the day though it is down to her to make the ultimate decision. I am hoping if she stays at home that it all goes well for her.
