I have Medela PIS that I purchased with DS. I purchased it after I had DS (was previously using a used one that went out on me so I bought a new one) and only used it about 4 months when I stopped nursing/pumping. Bought it brand new. Now that I'll be using it again, do I need to replace everything?
I just took it out to look at it and everything still looks fine. Some water spots in the tubing and on the breast shield. Should I also replace the bottles that came with it?
