Yeah, it looks like the courses generally start 8 weeks before your due month, which probably works better timing-wise for those due at the end of the month than at the beginning. Some branches do courses for due dates which range from mid-month to mid-month, which I think would suit me better, but mine doesn't.
But given everyone says the most valuable part of NCT is the local mom-friends you could make, I'm not sure if I want to be amongst the first or the last in the group to give birth, so comfort aside that's what I'm currently mulling over to see if I should go for the November or December due date course...
