With regards to out of hospital births, there is the risk of complications to mother and baby that would require rapid lifesaving interventions. Its a statistical fact that some newborns will require aggressive resuscitation and some mothers will have life threatening complications.
Ezras Nashim volunteers are reportedly trained to deal with those types of emergencies (e.g., they are certified in neonatal resuscitation). Is it your argument that they are not? Or is it something else?
