Thurbersdog - it was me, not blacktea! MY HV sounds like yours... very very pro bf in the early months, now thinks I should be giving no more than 1 or 2 in 24 hours (and also thinks I should have nightweaned DD, now 11 months, at 6 months....) 
Grumpy - that is really helpful, thanks. I don't DD for a full 12 hours every week day (I work fulltime while DH is a stay at home dad), so I am hoping against hope that is enough (I would in an ideal world like to keep bf until DD is about 18months... no idea why, just because that's what my Mum did for me!!!). I am greatly encouraged by the fact that, although my cycles have been all over the place, I am getting AFs (had about 4 now)... so fertility must be on its way back at least.
Excuse TMI in advance, but...... I have NO IDEA what AF is doing right now. I thought I was finally ovulating a week late (CD 20), but instead of the usual clear, eggwhite stuff, (ahem, actually a bit embarrased now), it was mucus-y but dark, as if mixed with old blood... thought it was maybe AF a week early, but no... it only lasted 2/3 days. Very odd. I guess a late ovulation with muckier than usual EWCM. Nice 
Still, if AF turns up in 2 weeks, I guess all is fine, its just a 5 week rather than 4 week cycle at the mo. I can work with that!!!
ps - Grumpy I am also very encouraged by the frequency of your DC's breastfeeding generally! DD adores my boob and I am sure that if I weren't at work, she would feed 12 times a day (she crams about 6 in during the 13 hours I am at home overnight!).... I generally don't let on how much I feed to anyone in RL as they are always rather shocked and think I should "do something" about it...
