For WOHMs, what did you find optimal (or wish you had gotten) as far as collection bottles, spare flanges, etc when you returned to work? I will likely need to pump at home before I leave for work in the mornings and won't have the time/desire to wash those parts before I go, so I need at least one spare set -- but should I get another for good measure? I kind of like the idea of having one set always at home and two sets for the office in case I don't get to wash them one night or something. But maybe that's overkill?
