Natasha,
I am also a BF ma ma but I am a working ma ma as well. My boy can be fed by bottle and direct. Before I came back to work, I asked other people, the maid and my hubby to feed the baby with bottle. He has been used to this way since then.
May be you try to ask other to feed your baby and let her get used to that first. If you want her to use bottle.
And I also find it is quite convenient to direct feed the baby in the street. You can go to 母乳喂哺, there is a topic about the place you can feed your baby in the street.
