I completly understand about the pain. I was so close to giving up a couple of times in the first 2 weeks. the cracks, bleeding, it was excruciating. If we weren't an hours round trip to the local 24hour supermarket, I would have sent DH to get formula at 2 am during the first week we were home! Then when he was 2weeks 1 day old it stopped. They only took a day and half to heal and it was so much better. I was so relieved not to be in tears at feeding time anymore. They were starting to get a bit sore again with this 2 hourly feeding, but I'm hoping that isn't going to last.
It's been great having DH home. He gets up to Noah in the middle of the night to change him and brings him to me to feed, then he burps him and puts him back to bed. It's going to be a shock to the system when he goes back to work in a week! I hear you on the day sleep. I have had a few, but I feel guilty doing it as when I do I literally feed, sleep and feed again. I sleep a bit longer in the mornings by going back to bed after his 6 or 7am feed so don't get up until 9am or sometimes 10am and then I usually don't bother with the afternoon nap.
