4 months and I think I’m done

After going back to work (I’m a respiratory therapist in a large hospital), LO decided she didn’t want to nurse anymore. I suppose she just got used to bottles since every meal on the days I work is bottle fed. I’m pumping as much as time will allow me to, which isn’t very often. I just feel very defeated and disappointed in myself. I’m really trying to adapt to the “fed is best” mentality, but everything in me just wants to breastfeed her. If I’d have known that the last time would be the last time, I would’ve enjoyed it more. Guess it’s time to attempt to transition to formula.
