I get the impression that the nature of a local NCT group is just going to be a matter of luck, I don't know mine. My postnatal course tutor seems to be the NCT contact for everything in Haringey that doesn't have someone else to run it, and she doesn't actualy live in the borough, but a few minutes the other side of it.
I have a friend 5 mins walk from here who found the local NCT quite stuck up and snobby when she tried contacting them, however, her sons are 18 and 13 so I suspect there will have been some change in the people involved since then. I hope so.
Captain Dippy, maybe you should train to qualify as an NCT tutor, though I guess time might be an issue for you.
I would like to get involved in NCT stuff in my immediate area, if there's something to get involved in before my maternity leave ends.
The Haringey Local website on here mostly has links at the moment to quite expensive private classes and actitivities in the west of the borough (that's the posh bit, where I don't live). If I can find out about stuff nearer to here, I will have to suggest some links myself.
Tomorrow is the Breast Feeding Network drop in group, which is open to women to come along with their babies and toddlers, it's there to encourage breastfeeding but it doesn't exclude people like me who wanted to but failed.
