You can try to substitute 1 feed with the bottle and while Eva is on the bottle for that feed, you can pump. So for now to get that 1 feed, you could maybe pump right after each latch to get the amt for that 1 feed at night. You can get your hubs to feed with the bottle for her to get accustomed to someone else, apart from you, giving her food.
What I did 2 weeks before going back to work is to pump after every latch and to either keep or make up the amt to feed at night. When I am really out, I feed FM. I'm using NAN series of milk which my paed said is one of the most similar to breast milk.
I also bought different bottles (1 of each) recommended to try. I have NUK, Avent, BFree and Pigeon. My boy liked Avent the best. I think now the other bottle that is "in" is Tommee Tipee.
You can just feed her with the straw if she is fine but you must make sure your caretaker cleans is properly after every feed because straws are harder to clean out and milk is "oily". The other way is to use a spout cup where the flow is faster.
The problem with teats is that the flow may seem too slow once your kid grows and can make do with a faster flow.
