How do i get my breastfeeding baby to take a bottle?

My lil girl is 2 months old and i exclusively breastfeed her, she wont take a bottle for nothing, i even tried tricking her n pulln her off the breast then sticking a bottle in her mouth but she knows and starts screaming til she gets the breast again. I have also tried pumpn my milk n she still wont take it, its the bottle nipple that she refuses! Is there something i can do or something out there that is like the real thing! It sucks being the only one that can feed her and it gets hard sometimes! I cant be away from her too long cuz she rather starve then take a bottle wen shes being babysat!!! Any advice would be great!
