Re: Help me not quit...
Welcome and congratulations on the new baby! I am sorry you've had such a rough time so far. How are you feeling? 7 days post-c-section is probably still pretty painful... I hope you're taking the advice to do nothing more than feed the baby and recuperate.
I think you are doing all the right things to get nursing back on track. You definitely need a good pump, and you're going to want to use it frequently. 8-12 times in a 24 hour period, or as many times as it takes to get your baby's needs met. As long as you can pump everything he needs and not supplement with formula, it will be easier to get him back to the breast. Until the PIS arrives, use that manual pump as much as possible, and contact the hospital and ask about getting a hospital-grade rental pump (which would be the ideal pump for your needs). The manual pump will probably not yield much- they are really best for occasional use by moms with established supplies. But you can in part make up for the relative ineffectiveness of the manual by pumping more frequently.
At 7 days out, it is unsurprising to see yellowish-white "transitional" milk. When milk is first produced, it still contains an admixture of colostrum. However, if what you are seeing is pure, transparent yellow, not yellowish-white or cream-colored, then you are still seeing colostrum. That would be surprising at 7 days out, but not unheard-of, especially considering your difficulties with nursing and the fact that you've been supplementing with formula since the beginning.
I think it's excellent that you will be calling the LC. You definitely could benefit from hands-on professional help. I also suggest calling your local LLL leader and asking for the name of a good local IBCLC, since the hospital LC may be just a nurse with some additional training and you really need an expert!
This link talks about getting a baby to the breast: http://www.kellymom.com/bf/concerns/...to-breast.html. In particular, the skin-to-skin and instant reward techniques are useful. You also want to consider using a method other than the bottle- like SNS, Lact-aid, syringe, finger-feeding, etc.- to feed your baby. Babies love bottles because they are so easy, which is why general recommendations are to delay the introduction of artificial nipples until breastfeeding is well-established. Which is something I throw in not because I want you to feel guilty about using a bottle when you needed to do so, but to explain why things may have gone off the rails.
Since your baby pulls off the breast and struggles so, it may help to try swaddling him. The SNS or Lact-Aid may also be very useful since he will latch, and probably pulls off because he doesn't like the fact that he has to work for a meal at the breast. With the SNS, he'd get an instant reward and potentially stay on the breast a lot longer.
