I believe lots of hospitals are pushing this as a way to push for higher breastfeeding rates, which is no problem for those who have decided to BF but causes a nightmare for those who choose not to.
Saw on another post that you can get bottles of milk made up already (which are sterile until opened i would presume). Not sure if baby can feed from these or if you need another bottle to put the milk into, perhaps someone else can answer this. Considering that unless there are complications, your hospital stay won't be that long, perhaps that might be the best option.
Sorry I can't be more help, but all my research so far has been about BF.
