So I did my thing last night, pumped around 10, steam cleaned the parts for today, dried them off, put them back together and put them in my bag.
I just finished my first session at work today. I go to rinse out the parts. Lift up the membrane.
OMG THERE'S A DEAD EARWIG IN THERE.
WTF??? It must have crawled in overnight.
Of course, it was my first session of the day and I'd already combined the milk into one bottle, so there goes 5+ oz down the drain.

Re: My pumping fail of the day (rather icky)
Ewwww... I effing hate earwigs.
I found a dead one under my coffee filter once. After I drank the coffee.
ewwwww
