How do you store your breast milk at work?

teachingmommy

I'm going back to work on Monday (so sad to leave LO!), and I calculated that I will be pumping around 30 oz while out: 2 sessions while driving there and back and 1 session during my 30-minute lunch break. The only fridge available is not nearby, so I am considering storing my milk in a cooler or some type of thermos. Has anyone tried storing in something besides the fridge? Advice, please!

Also, our sink is far away. Has anyone just used sanitation wipes to clean off pump parts, and then did a thorough hot, soapy water cleaning once at home? Since I am a teacher, I have very little time and am trying to think of ways to be as efficient as possible.

 Thanks, ladies!
