Help - baby refusing bottle

Jessica

Hey all - baby girl is 14.5 weeks old and has been primarily breastfed since birth. However, early on she wasn’t gaining much weight and we were initially supplementing with formula until my breast milk came in fully..... she had no problems going between bottle and breast at that time. However - once my milk was in completely she became an EBF gal and had been up until beginning of November when she stayed with gpa and gma for a couple days and had bottled breast milk. At that time she also took the bottle easily with no issue. Since then she again has been getting primarily just the breast, and she has begun in the last week or so to completely refuse bottled breast milk. Can anyone give me any ideas on how to help her get accustomed to a bottle again?? It’s really hard because like tonight for instance we had a date night just hubby and I and we had to cut it short so I could go home and feed baby because she refused the bottle from gma... please help!!!! 😬
