I'm a professor and frequently write at neighborhood coffeeshops for four or more hours at a time. I usually have a laptop and lots of books with me. The coffeeshops nearest me only have single bathrooms, so when I go in to pump I'm basically monopolizing the entire bathroom for however long it takes. I try to pump quickly and get out. I'm not worried about people judging me or anything. I'm proud of what I do to feed my daughter. But I do feel slightly guilty about taking up the only women's bathroom for 10-15 minutes at a time.
Thoughts? Some nursing moms suggested I could pump in the car, but that would mean packing all my stuff or at least my computer and so on to leave the coffeeshop and sit in the car in the winter. I use the Medela Harmony while out and about and can usually empty both breasts in 10 minutes or so (though I miss a second letdown this way).
