My tricks from DS who refused a bottle even when I had no milk. I tried them all
Try feeding her when shes asleep till she gets used to the bottle again. I used the 10pm feed. (This is the trick that worked best for us!)
Try a bit of boob to take the edge of her hunger then try slipping the bottle in. this one took a few tries to trick DS.
Stick to one bottle when trying tho, otherwise its too many changes.
Given shes used to take the bottle there is hope she will go back to it.
Good luck.
