Sterilizing bottles/pump parts?

Emily

It just occurred to me today that maybe I should sterilize all my bottles and pump parts? I wasn’t planning to do this until after baby because I don’t plan on pumping or bottle feeding until 6 weeks PP. Dad is overseas so he won’t be feeding baby those first 6 weeks anyway. But I also know things can go unplanned. You ladies who are planning to exclusively feed at the breast, are you still sterilizing anything or just waiting until you need it?
