Thanks everyone. I will order the band from Amazon, a friend also text recommending one yesterday too. I will also try the peppermint, Showofhands, as I have tonifht had to switch to formula. Unfortunately my milk has just not 'come in'
After (at least) 3 or 4 very painful attempts on each breast at about 11pm, a frustrated baby and nipples on fire I asked my OH to make up a bottle. He grumbled a bit but think he saw in my eyes that I was in the edge, and more important than that we have a 4 day old who has lost 8% of her birth weight.
The main pain now is sleeping, post c-section wise. I can't lay on my front or either side and even flat hurts after more than an hour. So I'm sat up in bed which isn't great. Im no longer struggling with number twos (apologies TMI) which is good. My mum has been an absolute angel coming over and helping me whenever I've asked. The baby is worth this discomfort and a million times more, of course.
Just can't wait to be able to sleep in a normal position now, I didn't have it for so long in pregnancy and now since that it's going to be wonderful to get that back.
Thanks all for your tips, advice and support 
Anyone got any experience of the problems in sleep positions post emcs they'd can share?
