I'm going to try to reply in an organised post rather than quoting massive blocks. Thanks everyone, so much.
@Journeyintomelody - oh, yes, I did the handbag thing with DD! It just made my brain feel more in gear somehow.
And good point that every baby is different - and thanks also @SatinHeart and @Rarebitten. I keep thinking I have to remember everything from when DD was a baby, and actually, if I do manage to have another, it'll be a totally different baby. I guess that cuts both ways - all sorts of things might be easier this time! Live in hope, right?! 
@Rarebitten - good memory! I worked in Dublin a couple of years ago. But I'm actually in North Yorkshire. I might do NCT again, just because I am one of the lucky people whose NCT group first time round were actually lovely people (still in touch with most of them). Plus I suspect I missed all sorts of things by virtue of not being the birth mum. I am smiling at your point about Naomi Stadlen (and so jealous you did her group!) as my wonderful Mumsnet friends, whom I've now known for well over a decade (coming up on 15 years for some of them) sent me 'What Mothers Do' when DD was born. I am re-reading it right now!
Your busy life with your newborn sounds amazing but I do take your point! I definitely did too much when DD was a baby - I had to; we ended up in a rather unexpected situation with work and life - but this time round should, in theory, be less frantic out of financial necessity.
@Ghouella, thank you, that is such a useful point! I had been quite tempted by co-sleeping. I know it can be safe if done properly. First time round DP (ex-P) was very anxious and didn't want to, which was probably sensible as she was on medication early on and didn't wake up easily, so it would have been a non-starter then anyway. But I do like the idea.
@CurlewKate, no that doesn't sound crazy at all! (And nice to see you on here!)
@GiddyRobin - ooh, yes, excellent practical solutions! Thank you!
@Rumforme - such a good point; I must keep that in mind. I know how easy it is to slip into 'too hard to do that today' mode.
@LysHastighed - oh dear, yes, I am a bit concerned about this too. I know a friend of mine who was a single mum by choice when our babies were tiny, said this of her NCT group. They were not deliberately nasty, but it was as if they couldn't truly process that she was on her own! That's a really good idea about taking this year to find some other nice groups. Thank you!
@Echobelly - thanks! YY, not fixated on breastfeeding. DD was combi-fed from the start (she was tube fed in hospital, so EBF was out of the window). I would absolutely do that again for preference, and it'll make it easier with this baby's dad (he's in the picture; we're just not together in any sense).
