i ep'd for 2 years with 1st LO using a medela PIS original. now we are expecting #2 in a few months. it will have only been about 5 months since i have used the pump or the pump parts.
do i need new breastshields, personal pump connectors, membranes, etc. for safety/sterilization/sanity reasons? is it safe to use the old ones?
what about new medela bottles?
i have purchased new tubing, but am wondering if a good sterilization will be sufficient for the old pump parts? if so, what qualifies as a "good sterilization"? thanks!
