Ask the Expert Series: Breastfeeding

Hi, i gave birth 2 weeks ago and have trounle latching my bbg. I have short and inverted nipples. Pumping prior to latching does not seem to help, so does nipple shields. If i try and DL her, she ends up biting on the nipples and getting very frustrated. What can i do to be able to breast feed my bb instead of exclusively pumping?
