What sort of pump would I need if I'm trying to suppliment ebm for my lo who won't stay on long enough to get as much as she needs. I'm thinking she may have a latch problem and isn't draining my breast well. I want to pump to make sure she gets enough at each feeding. I would probably nurse on one side, switch to next breast and then pump on first breast while nursing on second. Then finish up pumping on second breast, and immidiately offer the expressed milk. I also wouldn't mind having a reserve. I don't work outside the home. Any help on brands,styles, and techniques would be helpful.
