Perhaps you should just let the baby latch on all she wants and continue pumping either before or after her feeds. For myself, I did that for EVERY feed for the first two months and I realised that all the pumping actually made me very tired and the milk supply went down instead. So after that, I only pump about 3-4 times a day or when I'm not too tired. I also set a target of 300ml to hit everyday. You can do that too! My EBM bank is now full of milk which is sufficient for baby to take for at least 20 days.
Try to bottle feed her only once a day to let her get used to the bottle.
