Breastmilk is best for babies.

I'm having a difficulty in giving my baby breastmilk after 1 1/2months of no feeding due to my medications for my blood pressure after giving birth.thankfully i still have breastmilk thanks to electronic breast pump.but now she's used to feeding bottles that i'm having a hard time getting her to latch so she can drink from me and so i can produce more breastmilk.what can i do???
