I have had a somewhat similar experience re breast-feeding: every time I mention dd's failure to thrive and subsequent hospitalisation, somebody is bound to pipe up with "oh if you had only had better support/oh if breastfeeding was only more normalised, it would have been totally different for you". I had every reason to believe I would be able to make a go of this:
*I come from the country with the highest breastfeeding rates in the world!
*Everybody I knew breastfed.
*I attended one of the most breast-feeding friendly hospitals in the country.
*As I was also in for ante-natal complications, I had multiple extra opportunities to access breastfeeding preparation- and I made the most of those.
*I went to an ante-natal group that was very supportive and positive about breast-feeding.
*When dd was born, I had a nurse sit by my bedside at every feed to help me latch on and get her to suckle.
*Dh loved the idea of my breast-feeding and did everything in his power to support it.
*Parents and ILs all supportive.
*When things started going pear-shaped, I had support from a specially trained breast-feeding counsellor, courtesy of the NHS.
And this is what women's bodies are supposed to be able to do, right?
Things went wrong because despite everybody being totally committed and supportive, dd was born with a hidden disability. Her body did not do what it was supposed to! Some bodies don't. (hers still doesn't always)
When people whaffle on about Nature and what Bodies Know, I always wonder if they've ever watched a wildlife programme in their lives. Nature is a bloody harsh place! Giraffes get stuck in the birth canal, little gorillas die from failure to thrive, lions suddenly turn on their cubs and eat them.
