Is it better to rent or to buy a breast pump?

It depends: Some mothers find renting a hospital-grade pump to be very efficient for breast pumping (you will need to purchase the sterile nursing equipment separately). However, if you desire to pump at work, it may be convenient to purchase a portable pump that is easier to transport discretely from home to work. Furthermore, some mothers find manual pumping to be reasonably efficient and less expensive.

Yes and no.: If you can afford to buy and you plan on using it often and/or for multiple newborn/infants go for it. Renting is also just as good but the equipment is not yours to keep. You can always pass it on to a friend if you buy (or buy from someone you know).
