FWIW at this stage :-)
I think that “to bear down” and “to push” are used interchangeably and that clear distinction as in #12 is not actually valid. I think you will find as many examples of an instinctive “urge to push” as there are of an “urge to bear down” (= “Pressdrang”?). At risk of being indelicate, many women describe the sensation as an overwhelming urge to empty the bowels/go to the toilet, which is not really surprising as the same muscles are involved. I think that “bearing down” is sometimes used to make the procedure sound more natural and to distance it from directed pushing (the “old way”), as in the OP.
Royal College of Midwives guidelines 2012:
“There is no evidence to suggest that women need to be taught when and how to push (NICE 2007; Bloom et al. 2005; Sleep 1990). The practice of sustained breath holding in directed pushing may be harmful (Prins et al. 2011; Cooke 2010; Yildirim and Beji 2008; Thomson 1993). Women should be given confidence in following their
own urge to push.”
http://www.evidence.nhs.uk/search?q=directed%...“A better approach based on current evidence is to delay pushing until the woman feels the
urge to push.”
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1...“A new study is raising questions about one of the most accepted practices in the delivery room: urging women
to push during contractions to help the baby come out.
The researchers, writing in the current issue of The American Journal of Obstetrics & Gynecology, say there is no evidence that
bearing down during contractions helps either the mother or the child.”
