Thanks so much for your encourangement and advice. I saw the lactation nurse at the hospital today & baby and I were finally able to nurse successfully! What a relief.
Turns out it was a latching issue. Her lower lip was turned inward rather than outward & was frustrating her to no end. Now I need to master the "lower lip flip", lol. We were even able to nurse for a session when we got home. It wasn't as pretty or easy as when the lactation nurse was helping but we managed somehow.
Can anyone point me to a good resource for how-to's on the lower lip flip? I'm searching through google now but not finding what I'm looking for.
