Hi Mama!!
First, congratulations on making the decision to try and nurse/breastfeed. Second, good for you for asking such important questions!!
I have nursed both my children, and I am preggers with number three. My daughter, our first child, was by far the hardest for me. I had a ton of pain also; however, everyone who observed us said she was latching well. I was at a lost too.
What I learned was that I had microscopic tears or cuts in the breast tissue. I did a few things that allowed me to heal and improved our nursing relationship.
(1) I ditched the nursing pads - they were keeping too much moisture against the breast. I purchased these "sports-bra-like" wrapped-styled nursing bras that were cotton and very thin. (I hated the idea of being "uncovered"). You had to pull one side over at a time to nurse.
(2) After she was done nursing, I would rub the residual milk over the nipples and then I applied a triple antibiotic ointment. This I carefully washed off immediately prior to the next session.
(3) I also used Medela Soft Shells for Sore Nipples (http://www.target.com/gp/detail.html/183-###-###-####-###.... These helped because it allowed the milk to drip and while the breasts stayed dry.
(4) I also used "Gerber Warm Or Cool Relief Packs" in order to numb the breast tissue and reduce the pain I was experiencing. I could not wear them too close to a nursing session as the cold reduced my milk flow but they helped immediately afterwards.
Now, as for being hungry 10 minutes after feeding, I learned about something called cluster feeding. My little girl LOVED to do this to me! Basically it means that she can feed for 10, rest for 10 and come back immediately for more. Continue to offer yourself to her. Your body will adjust accordingly. This is apparently common, but noone ever seems to tell new nursing Mamas about it! I was shocked. Google it. You'll find some comforting info.
And, lastly, pumping is a great thing. To build a frozen supply, especially before your body "regulates down", I would pump after a session (assuming she is not cluster feeding). You may not get much - just an ounce or two, if you are lucky. Don't worry. It will pick up. I also used my pump to reduce engorgement. This usually means a huge amount of milk. I use the "rule of 5" for storing milk - 5 days in the fridge, 5 weeks in a freezer attached to a fridge and 5 months in the deep freeze freezer. We are lucky enough to have an upright deep freeze freezer so we put all the extra in there for when I go back to work.
The one thing to note is that pumping may give you a break from physically being connected (and give Daddy or someone else a chance to hold baby and bond while getting her use to a bottle!!); but every time your baby feeds, you will need to pump. This is a good rule of thumb to maintain your suppply. For this reason, I generally took the night feedings since I would have needed to pump anyway and it did not make sense to me for both of us to be sleep deprived (especially once number 2 was here! LOL.)
If you have any other questions, feel free to message me. I think BF-ing is the greatest gift in the world and am more than happy to help out another Mama.
