WOAH!!! I wasn't expecting such great feedback, thank you.
I appreciate everyone's opinions even though some comments seemed to be worded a little harshly, even if it wasn't meant to be read that way.
Only 2 days after being sent home from hospital I had to call out the BF specialist as LO had made both my nipples bleed which made me cry with agony as I was feeding him. I had to give him formula while my nipples healed.
I've already got a tub of Lansinoh cream which I agree is very good.
I've been expressing since day dot and yeah it does help loads although some days I get a lot more expressed than others.
I've tried the nipple protectors but not for a while so I might dig them out again, now my nipple feels about 10 inches longer they might actually fit!!

(And yeah MrsD they were Boots own so I may have to invest in the Medela ones)
I've got 2 V pillows which I couldn't live without, although I've found today that I think the stretching sideways to pick him up is causing pain in my belly as well.
I'm going to try a different position and maybe have a look at that c section belt, I've never heard of one of those before, thanks for the link michmummy. I'll probably give the HV another call next week too if it carries on.
As I said, I appreciate everyone's comments and advice and Dangermouse, thanks, although I'm sorry to hear how things worked out for you I appreciate you giving me a different take on it. I hope everything's ok with you now. I must admit, the day I had to give LO formula because my nipples were cracked did make me feel isolated from him and like I wasn't needed anymore.
