I have been renting the Symphony ever since my twins were in the NICU last year. However the costs are adding up quite a bit (15 months worth.) I am thinking of changing to the Pump in Style, but wondered if that would cause a dip in what I can pump out while I am working. I already feel like I am hitting a wall again with the hospital grade one even with new membranes and such. My breasts are full sometimes, but I just cannot get a good letdown or two to get it all especially overnight. I get up to pump since I am full and so it is extra milk they can drink ( don't want my supply to tank!) Has anyone changed pumps or had experience with the Pump in Style?
