Hi C.,
I am not sure why you feel bad for your new baby (congrats, btw!!), babies have nursed from mamas with all different sizes of nipples for centuries!
I would just be real careful that she is latched on correctly. sounds like she is doing OK since she's getting the wet/soiled diapers; just keep her in that good habit.
You could also contact La Leche League with your questions, they "wrote the book" on breastfeeding "The Womanly Art of Breastfeeding". Their website is www.llli.com. You can call a leader with questions and/or attend meetings even if you are not a member.
Best of luck to you, and enjoy your new little one!
K. Z.
