A friend of mine just had her baby a month early and went through a great deal of trouble to get her breastfeeding relationship established while babe was still in the hospital. He's doing well now, but in a few weeks she is going to have to go back to work. She bought a Medela single pump which didn't work very well for her. She borrowed a hospital grade from the Health Department which worked great but she can only keep it a short time. Are there any sources of good quality breastpumps for not too much money for a mom in her situation? I know some breastpumps like the Pump in Style are not meant to be used by more than one person, but are there any that CAN be bought used? Any suggestions would be appreciated!
