It's an obscure question, google didnt give an answer. I'll try keep it brief..
During birth, midwife would wipe 'down there' with cold water(?) before every internal exam. My question is why? Cant recall the reason if one was given and only happened once out of three births.
(Someone was discussing birth debrief earlier today, and it reminded me of this, as it's one of the only bits during giving birth that i never really understood.)
