Just a note on what I heard - Automatic ones are better than manual and do the job in half the time. Hence, I am thinking of an electric one as I plan to either work from home or return to work. My only worry was the feeding bottles. Can the BPump and bottles be of different makes? If so, will transferring be a problem? I have kind of settled on Medela swing ass the reviews were good. Waiting for other moms to give their thoughts.
