I think you have to look at the original aims of the association back in 1956 for the NCT to understand where the charity are coming from. From their website:
'The original aims of the Association as published in 1956
1.That women should be humanely treated during pregnancy and in labour, never hurried, bullied or ridiculed.
2.That husbands should be present during labour if mutually desired.
3.That analgesia should not be forced on women in childbirth (and) nor should labour be induced merely to save time.
4.That more emphasis should be given to self-regulated breastfeeding and rooming-in allowed if the mother wants it, and that future maternity units should be designed with this in mind.
5.That a mother trained for natural childbirth should be allowed and encouraged to carry out her training fully during labour.
6.That all mothers should be encouraged to use natural childbirth for the benefit of themselves and their babies and that posters to this effect should be displayed at all antenatal clinics.
7.That the idea fostered by many medical people today that natural childbirth includes routine internal examination, routine administration of analgesia, routine episiotomy should be dispelled.
8.As childbirth is not a disease it should take place in the home wherever possible. If impossible the maternity units should be homely and unfrightening and in no way connected with hospital.'
From this I view it as mothers wanting to remove the increasing medicalisation that was happening to childbirth and taking back some of the decisions that were automatically being made. I feel it has probably worked to some extent and not in others - If a woman has been able to receive information to make an informed choice about having an epidural then surely the charity have succeeded in it's aims? That it is the woman making the choice and not having it forced on her?
I think to take some of the fear out of childbirth is a good thing? And removing the medicalisation of birth can help sometimes? Although it is true that sometimes information can have the opposite effect depending on the individual - and that some individuals will want birth to be medicalised.
It is true that birth has been made 'safer' when you consider maternal deaths ( and that of the babies). However I believe not enough is now being done to consider the psychological implications - ranging from birth trauma, PTSD, PND to the overwhelming guilt discussed daily on these boards either felt or implied. Epidurals have their place - I feel the NCT acknowledge this, unfortunately individual teachers may have their own axe to grind and participants should complain if they feel a subject has not been dealt with.
However if you don't like hearing about the negatives associated with epidurals in a class and end up having one anyway it can be a real challenge to reflect on this after birth. We as mothers have to deal with 'negatives' all the time and this is not always easy especially as we can be our own worst judges!
