There are several types of breast pumps on the market today made by a variety of companies. The choices can be overwhelming.
Some pumps are better at establishing a milk supply then others.
See the chart below for more information. If you do not plan on pumping too frequently, you may want to consider hand expressing or using a hand pump. Also ask yourself if you plan to pump on one side while your baby nurses on the other. If this is the case, you'll want a pump that can be easily operated with one hand. If you plan to pump at least once a day, you may want to consider an automatic self-cycling electric pump.
