Has anyone ever successfully negotiated pumping and saving breastmilk on a business trip? I'm going to be gone from my 1 month old for five days next week, and I'm wondering if there is any way I could possibly make it through without having to dump everything out.

For part of the trip, I'll be at my sister's house. So refrigeration won't be a big deal. I think if I just keep it refrigerated/cold, then freeze on return? I'm envisioning stuffing my suitcase with a collapsible cooler and ice packs...

I don't think shipping it home will work, since there isn't really such a thing as overnight shipping all the way up here...
