I have an upcoming business trip to London in October. I'm DESPERATELY trying to get enough of a stash in the freezer before I go (although it's not quite working yet. I have about 45 days left to get 40 bottles into the freezer, wish me luck). But my big concern is that while I'm in London, I'll be pumping and freezing my supply but I'm SOOOO worried that they will not allow me to bring my pumped milk back into the states. I'm having a hell of a time researching whether or not if/how I can bring back my milk. I reached out to the TSA but they gave me some canned BS answer that DIDNT answer my question or really explain anything.  I would be heart broken to have all my hard earned breast milk be thrown away at Heathrow airport right before I return home. Plus, by the time I get home, my son will have just depleted my (hopeful) freezer supply so he won't have anything to drink since he refuses formula. Does anyone have any advice for getting the milk home? PLEASE HELP! 

Thanks!
