How do you handle a night out?

Rachel
A friend of mine is supposed to be getting engaged in nyc this weekend and I want to be there. Getting someone to babysit isn't a problem but I'm thinking about pumping while I'm out. It seems annoying to bring the pump besides needing to get a battery pack for it but I know I can't go all night without pumping. Just wondering what experienced breastfeeders do 😋
