So the only unusual thing was that unlike in a "normal" home birth the midwives werent there all the time.
you clearly know nothing about homebirth. In fact your knowledge sounds similar to that of my Dad.
Point 1: Scans are one of the ways that it is determined that you are low risk
Point 2: Regular checks, as above determine you are low risk
Point 3: The MW checks baby's heartbeat regularly in labour towards the end a lot, more than in hospital because they need to be sure all is well.
Point 4: the MWs carry drugs in case you heamorrage, the same that would be administered in hospital.
Point 5: MWs are specifically trained in recusitating babies
Point 6: A standard HB is just like being in a delivery suite, progress was written on the board of the local CLU and they were on standby for issues.
Things have changed since call the midwife. Homebirths are well planned/ monitored and that is why in the modern day with phones in our homes and electric lighting they are perfectly safe for low risk women.
