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 keep my pump parts in lock n lock container after each use and put in the fridge. I only wash and sterilise the parts when I reach home. But i bring 6 empty bottles to work as i usually go for 3 pumping sessions and double sides each time. The expressed milk are kept in the refrigerator and I put in freezer after I reached home. I'm using Pigeon fridge to go cooler bag.
