sabire completely agree with you. But must fess up to being an NCT teacher myself, and am finding much of the venom aimed at the charity I work for hard to take in silence.
I know there are different standards within the spectrum of NCT teaching out there, but the training is pretty rigorous (and it's a big no-no to use your own birth experience as any sort of reference). We have to be able to qualify all our teaching with proper research references, so everything I, or any qualified teacher teaches can be 'proved'. Also I give out statistics, local and national so as not to give any false impressions.
I can only comment on my classes, but I know that, liek the OP's teacher, I cover the full spectrum of possible interventions at every stage, including; CS, induction, assisted delivery, various forms of pain relief, episiotomies & tears, and scbu. I talk about the why and the how and whether it might be possible to avoid. I'm also fully aware that labour and birth are tricky customers. It's impossible to predict what will happen to any one woman, so my job is to cover all likelihoods, so that whatever happens Mum & Dad feel they have some understanding, & are less likely to feel panicked and frightened. I've been taught by the NCT to cover all these things, as well as the breathing, relaxation stuff - and yes, new baby stuff too.
The OP's post said that she was annoyed with the class, NOT the teacher. I think it's reasonable to feel annoyed with them, she gave up her time (very precious and hard to come by with a newborn) and didn't feel listened to, or that her experience was valued. However, hats off to that teacher for getting her in - she clearly did have in mind allowing her class 1st hand knowledge of the spectrum of experience of childbirth.
So with this in mind, maybe some of the earlier anti-NCT teacher posters could reconsider their responses? We're not out to persuade you all to eat lentils and give birth in a field. We aim to educate and prepare for whatever comes next.
& to whoever asked what the NCT offers that the NHS doesn't - the answer is 'Depends'. It depends what your NHS offers. Here our NHS classes, run by lovely midwives, cover pretty much the same topics, but they have 6 hours, I have 20. they have large groups of up to 30 or more, I have 6 couples. I have the luxury of getting to know my couples individually and tailoring my teaching & activities to their needs, they can't do that so easily. I can vary the exercises, they don't have the time. I can allow a topic of interest to go on longer so I can answer all the questions fully, they can't do that as they're more time constrained. And yes, I aim to create an ongoing self supporting group by the end of the sessions. Our Midwives can't do that with such large numbers. Your NHS provision may be different though?
OP, my experience is that as labour & birth approach, 1st time Mums aren't 'ready' to hear much about interventions. they tend to focus on the 'straightforward' labour stories they hear. This might be some kind of primitive protective reflex or something. However they will have heard your story and it will be valuable to them. I bet if you were to meet them at a reunion you'd hear them saying, "Oh yes, the epidural was just like that lady described" and stuff like that. Don't be downcast or disheartened. You did a great thing by telling them your story and many of them may have cause to be glad of it, I'm pretty certain your teacher was.
