There are so many different breast pump models on the market, and deciding between them can seem confusing. So many factors influence breast pump purchases. In my opinion, the biggest factors are budget and frequency of use. Every mother needs to weigh those factors before picking the pump that fits her lifestyle. Someone who rarely pumps may be content with a manual option or a single-pump. More frequent users generally want automatic, dual breastpumps. While hospital-grade breastpumps can cost hundreds of dollars, you can find high-quality occasional-use models for well-under $100.
