You can always find a way to make things work. I’ve forgotten bottles, ice packs, and covers but always managed to find a (creative) solution. Don’t be afraid to ask for the things you need. I’ve walked into Starbucks to ask for ice when I forgot my icepack. I’ve had hotel reception hold my milk because there was no fridge in my room and had them freeze my ice packs if there was no freezer. I’ve pumped in the back of a NYC restaurant dressed in a 1920s outfit while someone was doing the dishes in the same space.
