Hi, D.!
First of all, congratulations on your baby & your wonderful choice to nurse her!
I see that you've gotten a lot of advice. Most of it is very good. Some of it (2 in particular) was aweful (starting solids or switching to formula).
I would suggest that first, you read "Nursing Mother, Working Mother" if you have not already. It is quite likely that your baby will do something called Reverse Cycling (I think that's what it's called!) when, basically, she won't really eat much/at all while you're @ work, but rather "save herself" for when you get home & possibly increase nightime feedings (co-sleeping may save your sanity if you're welcome to that).
Also, I encourage you to start going to La Leche League meetings in your area, if you don't already. They're free & a priceless resource for fact-based information, support & ideas.
Lastly, you can try giving her the Adiri Breastbottle, if you haven't already. Many "picky" babies will take that more readily. You can get it online or right at Babies R Us. My EBF son actually took it really nicely.
I wish you the very best of luck in your continued success at breastfeeding your baby!
