I'm going back to work soon . Can the mummies share how you wash the pump parts in the office and how to transport the milk back home fresh ? What kind of cooler bags do you use ?

I just put the pump parts and bottles in the fridge for subsequent pumping sessions in the office. I use vcoool bag which I bought from taobao, abt $30 including shipping. It can store my pump as well and its insulation is thick and good! I put 2 ice sticks (which came together with my taobao purchase) to keep milk cool.
