I've never had one that nursed all the time- that WOULD be intense! I'm not breastfeeding this time, but I have a feeling this little guy would have been my first marathon nurser though. He eats three-four ounces every two hours and gets instantly angry if he doesn't get it RIGHT NOW. And, honestly, I think he would eat more often if he stayed awake more. he is growing like crazy and not spitting it back up, so I guess it's okay.
I hope your nipples heal quickly! It's so, so hard to nurse through pain. You'll feel like superwoman after you get through it though! Breastfeeding gets so much better with time. I'm looking forward to having another shot at it with the next baby....
