Hi all,
DS is only 8 days old and I already feel like a failure with feeding, I'm hoping someone can offer advice or a good old slap to pull myself together. I'll try not to make this too long...
DS was born at 36 weeks via forceps delivery. It was a quick labour but traumatic, with DS born with severe bruising and me receiving an episiotomy and a second degree tear. 48 hours after birth DS's blood tests showed severe jaundice and an exchange blood transfer was discussed, luckily dual phototherapy did the trick and DS spent the next 5 days in an incubator.
During these first 7 days DS wouldn't BF and the doctors put it down to pain caused by the bruising to his face. We cup fed DS and eventually managed to introduce BFing in small amounts, often latching for 5-10mins and 'topping up' with expressed milk and formula to give DS his prescribed '60ml every 3 hours'. While he was in the incubator we were only allowed to have him out for 30mins at a time so being patient and slowly workin with DS to establish BF wasn't really an option, sadly. 
Out of nowhere DS started feeding like a superstar. As soon as he was out of the incubator he fed for a good 30-40mins, removed himself from breast when ready and fed well every 3-3.5hours. The past 2 days we seem to have taken a huge leap backwards with feeding and Im questioning whether it's the best thing for us and I feel like I'm letting him down.
He now won't feed for any longer than 10-15mins and I've no idea if this is long enough for him (I'm used to knowing exactly how much he's getting each feed...) so am paranoid I'm leaving him hungry. MW weighed him yesterday and he had lost a little weight so I'm desperate to make sure he has gained for tomorrow's weigh in. I've tried both breasts and swapping regularly and he isn't interested. He's producing plenty of wet nappies but only 1 dirty nappy today. Additionally feeding is now agony, MW and breastfeeding counsellor both checked his latch and can't see any problems but I've sat and cried through the past 2 feeds. My nipples are bloody and I've developed blisters on both (I think they're milk blisters?) and I've ended up stopping after 5minutes in tears and giving DS to DH so he can give him expressed milk and, if desperate, formula. 
How can I move forward from this? I'm trying to express as much as possible but the pain is preventing me getting as much as usual. I'm using lanolin but it doesn't seem to be improving. His next feed is in 2hours and I just burst into tears even thinking about it. I know I'm all hormonal and its only been 2 days but I just look at him in his crib and he's so perfect I just feel like I'm failing him by even contemplating giving up BF so early. Help.
