My breast fed baby took a bottle when she was a lot younger without any problems. She's now refusing and getting extremely upset when we try. I go back to work in two weeks and am running out of ideas. Have tried different bottles, yoomi bottles which heat to breast milk temperature, different size teats, switching from breast to bottle and nothing seems to be working. I'm going to be away from her four days a week and am really anxious about her not having milk and also about stressing out my husband and mother in law on the days she's not in nursery if she's upset and refusing bottles. Does anyone have any ideas??!
