Hellobee Boards

I commute on the train and schlep the baby back and forth from daycare in the ergo and it's over 2 miles of walking a day in addition to the MTA--I don't know if that's as much of a pain as the bike commute, but it's a lot to carry and it sucked, so I get it (I think?). but I'd still do the ziplock bag and bring the parts back and forth to wash at home every night, because it really really sounds unsanitary at your work, and especially when the baby is young, you just have to be super careful about cleaning. if your pump stays at work, that's a lot of bulk/weight not to deal with, and the pump parts aren't that bad and don't really weigh anything. one thing that I found that I didn't mind slacking on that *really* cut down on bulk was I stopped using the Medela cooler that my Freestyle came with and I just put the bottles straight into my bag, so all I was carrying was 2-3 bottles of milk and the pump parts.
ETA congrats

@bhbee: I used to pump in one of our storage closets, it was not chic

@bhbee: doubles as a panic room

My pump room was a back office and it was far from the kitchen (sink & fridge) so I used the pump wipes during the day (4 pumping sessions at work), then I would rinse them out in sink at the end of the day and store in a clean ziplock bag in the work fridge. I would bring them home on the weekends to give to do a deep clean wash and sterilize.

I pumped into bottles, but then immediately poured the milk into bags. It was a lot less bulky to deal with 4-6 bags of milk instead of bottles. During the day I would keep the milk bags in the cooler with the ice pack. Sometimes I would put the mornings milk in the fridge, if I didn't think the cooler bag was cold enough.

If at all possible, get two pumps. I was lucky enough to have one pump at work and one at home, so I never had to carry the pump itself home, just the parts to wash and the milk.

You will figure out your groove, don't stress mama!

I just rinsed parts and stored them in a ziploc in the fridge between pumping sessions.

Each day I would bring one tall bottle, two short bottles and one set of pump parts. Pump using the short bottles, pour them both into the tall bottle, rinse short bottles and flanges, cap the bottles, bag the flanges, everything fits into the medela cooler bag, into the fridge. Next session, same setup. Third session, the milk stayed in the short bottles. I didn't bother with an ice pack because I figured the milk would be fine on the half hour commute home. I had several sets of pump parts, but they all got washed on the sterilize setting in the dishwasher.

I usually work from home because it's just easier and I can. But on days that I do have to go in, my lactation room doesn't have a sink or fridge--I carry my parts and milk in a cooler bag, with the parts in a ziplock and carry inside my backpack during my commute, which also includes picking up my kids and schlepping their stuff. I only wash the parts at night. The pump itself and the tubes stay at my desk.

do you have a microwave at work? I bought the steam clean bags from Medella and clean my parts in there. Just pour water (can be bottled from home or faucet) and pop in microwave for a few minutes then dump the water and you've got steamy clean parts/bottles.

maybe check your state laws for pumping accommodations at work? In IL they have to allow you access to a fridge and sink and private room (that is not a bathroom!) to pump.

I took parts home with me every night. We also only have a bathroom sink and no microwave. I would keep parts in the fridge all day.

I also used pump part disinfection wipes in a pinch.
