I just learned that I am going to need to travel for work for an overnight. LO will then be 12 weeks (ugh!) and is exclusively breastfed, and I pump for his daycare bottles. Any tips on how best to air travel with expressed milk? I'm guessing I'll have anywhere from 30-40oz (maybe more?) that I will want to bring home. I've got the cooler section of my pump that holds (4) 6oz bottles (plus an ice pack) and I have another old pump's cooler bag... also (4) 6oz bottles plus ice pack. Will I be able to bring this much milk through security? I've got plenty of freezer stash at home, so I'm not worried about him having enough in my absense. He's nowhere near sleeping through the night... so he's probably not going to like a bottle once/twice overnight.. (neither is DH, who doesn't have to get up now!). Would love any tips for pumping, being away from home and airline travel with milk.
