Zephyr, that vomiting is just not a good sign with your elevated BP. I feel like that other midwife isn't being quite as concerned as she should be. I'm glad your regular midwife is back today.
As for breastfeeding, first of all, I had horrible nipple pain that didn't really start getting better until 10 weeks in (I had a lactation specialist check for lip tie and tongue tie and my latch, and she said everything was fine), but after that, things seemed to be going okay, and then all of the sudden DS went on a wicked nursing strike. I'm talking, screaming, arched back, complete freak-out whenever I would try to feed him. Once he started drinking, we were usually okay (unless something distracted him and he unlatched, then we'd start all over again, and with a young toddler around, there was a lot of distraction). The problem was, I was so desperate for my milk to start flowing so that he'd start drinking, but all the anxiety ended up making my let-down take FOREVER to happen, so I'd be sitting there crying desperately, "C'mon milk, start already! PLEASE!" but it wouldn't happen soon enough, and then he'd freak out. For a while, I could get him to eat if I was walking while I nursed, but after a while, even that didn't work anymore. In all, I went through 6 weeks of that hell and then finally he went an 8 hour stretch one day without eating and I said, that's it, I'm done! I actually cried the first time I gave him a bottle of formula, because he drank so much and so peacefully. I felt like I had not only been torturing myself, but him as well. I felt a lot of guilt stopping, but after 4 and 1/2 months of crying almost every day over breastfeeding, I knew it was for the best.
