In a few weeks I'll be travelling for work and DH and DD are coming with me. We'll be gone for a week and for three of those days I can't guarantee I'll be there for her feedings, so I'm currently pumping a bunch for her. We're driving and the trip will be broken up into two 6 hour days. I'm thinking we'll bring a cooler, but I'm wondering if that will keep it cool enough/food safe? Once we're at the hotel we can use the little freezers in the mini-fridge, but even those don't get super cold.

I guess I could try to give her as much fresh milk that I can pump on-site and use frozen to supplement, but i'm worried pumping on-site won't go well for some reason.

Tips welcome!
