Natural childbirth has evolved to suit the species, and if mankind chooses to ignore her advice and interfere with her workings we must not complain about the consequences. We have only ourselves to blame.

Jowitt frames childbirth as an evolved biological process whose “design” generally serves the survival of the species. The quote cautions that when societies or medical systems routinely override that process—through unnecessary interventions, impatience with labor’s pace, or treating birth as a problem to be managed—there can be downstream costs (for example, complications, loss of maternal confidence, or iatrogenic harm). Her language personifies nature as offering “advice,” implying that physiology provides signals and constraints that deserve respect. The final sentence shifts responsibility from “nature” to human choice: if outcomes worsen after avoidable interference, the blame lies with the interveners rather than with childbirth itself.
