Although I have yet to attend a NCT antenatal class, I must admit my experience with them has been faultless.
When pregnant with DS in 2005, I booked the classes (can't remember how much they cost - possibly £160). Was living in SE London at the time. I went on to have DS at 7 months - before the antenatal classes started.
After he was born, I rang up and after a bit of negotiation - managed to get a full refund even though they normally would deduct an admin fee under these circumstances.
Even though I had opted not to pay an extra £40 to join the NCT, I was still given a call by the local 'new mums' rep who invited me along to any coffee mornings she held. Went along a few times - the women there were pretty middle class but very friendly and I didn't detect any snobbery. One black woman attended and as an asian woman with a northern accent myself, I never felt anything but fully included.
I didn't keep it up because I just didn't happen to 'click' with any of the women there. Ended up getting matey with the women I did baby massage classes with.
Now I am 4.5 months pregnant and have moved to Leeds. I got in touch with the local NCT group who sent me all the info I needed once I hit the 13 week mark. They charge £120 for an 8 week evening class of 5 couples. Not a bad price IMO.
Plus, for those on lower income, you can pay £20 or £60 at YOUR discretion. The decision is your's, not the administrator's.
I was very impressed.
I am yet to form an opinion on the classes but have no complaints about my dealings with them so far.
I have a feeling the running of local NCT groups does vary a huge amount across the country. Maybe they need to look at what certain groups do well and try to spread best practise across to other groups.
