I hope to try to breast feed and pump to supplement as needed. I am trying to figure out what pump to get. For my lifestyle and work I think it will be really helpful to have a wearable pump. With that, I am trying to figure out if just a wearable pump will be okay or if it is worth getting a pump like the Spectra S1 pump in addition to a wearable pump? Is it worth the money to have both?
