Re: Short-notice travel/field work
pumping under a cover (like a thin shawl or something) is relatively easy, and can be done in relatively public places if you're willing to put yourself out there like that (i pumped in jfk airport once under a scarf!).
if i were you, i'd want to have
- a really good hand pump, and maybe some of those instant cold packs that you can activate when needed in a soft-side cooler
- a pretty robust freezer stash (at least 5 days' worth, in case you get one of those 5 day trips without notice)
- a good double electric that functions well on batteries and/or the car plug
i think re: long-term supply, it doesn't matter so much that you maintain the same exact pumping schedule every day (like a 10, 1, and 4 pm pump) - but that you pump as frequently as you can, whenever you get the chance. if that's at 6 am, 8 am, and 9 am - ok, fine. after all, babies nurse like that! just beware of going too long in any one stretch, and try to make sure you get as close to 8 pumps in per 24 hours separated, even if at random intervals.
good luck! please let us know what your employer says and how the trips go.
