In response to Kathleen's post about the PNS - first of all - my apologies if this has already been discussed. As a rental station - I think it is almost unethical to even recommend anything but a rental pump for a mom with such a premature baby. You questioned: "Is anyone elso running into people who have been told that the PNS is a "hospital grade pump"? Probably lots lots of people. medela has an 8 1/2 x 11 in. info sheet on the Pump In Style which states: "The Pump In Style combines a hospital-grade Medela breastpump with the stylish good looks of a black designer shoulder bag." I think the PNS is a great pump for a working mom - in many cases, I've known it to be the deciding factor for moms to not wean. In those cases - I think it's great. But this pump for the mother of a preemie? No way. Maybe medela needs to make this clearer to their rental stations.
