I'm going to a concert in a few weeks. 5 month old will be fine with his dad and takes a bottle so no worries there. However I don't know what I'm going to do about my boobs! Any tips on how I can express? Will I need to express every feed he'll miss or will I get away with one? I'll be out for at least 2 feeds, maybe 3. I don't really want to take a pump with me but will if necessary but have no idea where I would pump.
