Do you have a strong let down, when you first start feeding does a lot of milk come suddenly? It might be too much for her and that's why she gets upset. You could try pumping or squeezing out for a couple of minutes before you feed her, just to make your let down a little slower.
Congrats on her arrival!
My only advice is that you look into renting a higher quality pump. By me you can do this through the hospital. You could always call your LLL to find out about that by you. They might have advice or even lend you a pump if they don't do this rental thing by you. It's something to try.
Also, it might be something in your diet that she doesn't like! I've heard that some babies reject nursing when mom eats cabbage or broccoli. Usually it's about gassy foods, but it could be she has a sensitivity to an allergen or something. BTW this is more folk-wisdom than medical fact but maybe ask the Dr or LLL about this possibility and play around with your diet.
AND I think it's great that you're supplimenting with formula even though you clearly want to breastfeed. It takes a lot of moms & babies awhile to get there with nursing, but so many moms are stubborn about not ever giving formula. It's great that you're considering your babies needs!
What a stressful situation. I can't offer up much other advice, especially with all the things you've already tried, as well as having seen a specialist.
When I was BFing Leo, especially in the early weeks/months, I found this website called Kellymom, very helpful. Here is a link to page discussing when baby fusses at the breast and possible reasons along with suggestions of what might be causing it: http://kellymom.com/bf/concerns/chil...while-nursing/. I really hope something there speaks to you.
Also, if you haven't tried contacting your local La Leche League, that might also be a good place to try for help. There are often local group pages on Facebook, so you could try searching there as well. The support they offer is really valuable.
Good luck with everything, you are doing a great job!
Thanks you guys. I'm just so frustrated >.<
I'll have to call La Leche. I did research on their page, but hadn't thought to call with my brain preoccupied with so many things! The cheapest pumps in my local Wal-Mart are upwards of 200 for a good one. The hospital I had her at says that they only give out pumps to moms returning to work or school so that's out for me. I'm not going to be going back to work anytime soon. Sigh.
I tried feeding her about 30 minutes ago and she pursed her lips like she was kissing it, then took the bottle fine. Sigh. I think part of the problem is that (and this might be TMI) I have fairly large breasts. They're up in the double D range, and I just think there's too much for her mouth. But obviously there's nothing I can do about that. Sigh. I'll try squeezing some extra milk out to make sure I don't just have too much coming at her all at once.
Another article link for you (if you have time)
It's from the LLL site and has tips for large breasted breastfeeding. Mine are also large (were bigger than baby's head when he was brand new!), so I understand how awkward it can be! I also struggled with over-supply, engorgement and a very fast let-down that would leave Leo gasping for air while feeding as the flow was so fast.
Have you tried lying on your side while feeding? Once you get the hang of its its really comfy and you have a hand free to keep the top part of your boob from squishing into baby's face while she tries to eat :) I'm sure there must be some videos on youtube somewhere as well with different techniques and tips etc.
