Most pumping-and-working moms spring for a hospital-grade pump with dual accessories kits. This device is worth the hefty price tag (from $200 to $300) because it empties the breasts simultaneously.
Skip the secondhand pump: you can pass viruses from one user to another, even with new accessory kits. Rental pumps have barriers to keep milk out of the motor, making them a safer bet.
A private place to pump is a must. The office bathroom isn't an appropriate spot, says Linda Wieser, a lactation consultant and La Leche League leader in Ann Arbor, Michigan. If you don't have your own space, ask your employer for an unused office or conference room.
Allison Orenstein, of Belmont, California, requested mini blinds for the conference room, which her employer provided. She stores expressed milk in the fridge that everyone else uses. "It was awkward at first," she says, but now "nobody bats an eye."
