I'm going through the same thing and it is heartbreaking! My DD is 3.5 months old and I just went back to work this Monday. DH is home with her for a couple of months until she goes to daycare, he's taking his paternity leave after me. I was EBF with the occasional bottle here and there until last week. We wanted to make sure she'd take the bottle with frozen milk before I went back to work, so we started to intoducing it to her again. When I came home from work on Monday, she refused to take the breast! She started to get fussy the week before, and now I really know why. She's fine with dream feeding, but it seems that the bottle is just easier for her and she gets what she wants much more quickly than with the breast. I'm using the Dr. Brown Natural Flow bottles with the wide neck. I'm curious to know if other bottles may be better for babies that prefer bottle over the breast. Also, I tend to only pump out 1.75oz from the right and .5-1 from the left. Does anyone know what normal output should be?
