i worked in daycare in the infant room. there were two breastfed babies who had difficulty taking the bottle.
for one baby who was not in my room, her parents bought a breast-shaped bottle
and that helped. more info if you google 'breast shaped bottle'. AFAIK
adiri is the only company that makes it.
the other baby just would not take the bottle AT ALL but obviously HAD to eat while she was at daycare. i would spoonfeed her the milk, but she was 4 months old. i don't know how to feed a newborn, but i hear that some people use medicine droppers or cups as alternatives to bottlefeeding. so this baby was actually in my room and so i had to figure out how to deal with this issue - i mean, if you are a 4 month old in daycare for 6-8 hours at a time, you NEED to be able to be fed. and i was the only teacher in the room (with 2 other infants as well) and sometimes spoonfeeding her was not an option as it took so long and the other children needed care as well. so, basically, at each feeding i would offer her the bottle first, then when she'd refuse spoonfeed her most of the contents of it, offer it again at the end, and spoonfeed her the rest when she'd refuse. each time i offered her the bottle, i would try to drip a few drops out onto her lips. it took maybe a week, but one day she just latched on to the bottle and drank it all up. within another day or two, she was taking ALL her bottles without any trouble.
so... basically, i think it can just take time. the breast-bottle might minimize that time for some babies, but i don't think it's necessary. i think just trying it - and making sure you are NOT AROUND when it is being offered - is good.
does she not latch on at all, or will she latch on, suck, and then get upset? because fyi i've also had a lot of breastfed babies in my classrooms who are particular about temperature. if the temp isn't just right, they'll latch on, try it out, and then cry and not take the bottle.
