DS1 is 20 months and DS2 is expected in the next 5 weeks. I still nurse him first thing in the morning - not loads, just a cuddle and feed in bed and then he's off and running about. Occasionally at other times if he's really upset or he's ill or hurt himself.
I'm perfectly happy to tandem feed if DS1 is still keen but I have some questions that my LLL book and kellymom aren't terribly specific about (maybe because everybody is different and there are no answers...)
(1) Engorgement - With DS my breasts went from 34E to 34H with DS1 and then settled down to 34G-ish (depending on the style) which is where they are now. I assume because I'm still breastfeeding they won't go through a change of that magnitude again, or should I be going out and getting a 34J bra? Getting fitted was no use as they said "oh you could grow 3 cup sizes" but when I pointed out I was still feeding DS1 they were stumped as to whether I would get any larger.
(2) Latching/nipple cracking/soreness etc - If I'm already feeding one, does that mean I get to skip all the initial "wearing in" with a newborn - is all that due to the fact that first time round I had never bf before and had to toughen up? Or does it have to happen all over again each time because it's a new baby and a new latch?
(3) Colostrum - I guess my normal milk will stop at some point and colostrum will come in - any idea when this is? Then colostrum will stop and normal milk will come back? Should I stop DS1 feeding while colostrum is in? 
To complicate it all I'm having an ELCS as DS1 was 4.5kg and ended up as an EMCS. Even the midwives have discouraged trying for a VBAC - DS2 currently measuring 3kg at 33 weeks and estimated to be 5kg+ at birth. I assume there's nothing more I can do than demand that DS2 is put skin to skin straight after birth and refuse to be parted from him in order to get him nursing successfully after an ELCS but if anyone has any words of wisdom on that, please chime in!
