Re: 3-days away from LO. Pump?
Pump! I know it's a PITA to haul the pump around with you, but if you get engorged after one workday, imagine what 3 days of no milk removal could result in! If dealing with the lipase issue would just be a giant pain when you're on the road, I would simply pump and dump, because it sounds like you don't really need the milk that badly.
If you can leave a few bottles of milk, that seems like it would be a good thing, but not an absolutely necessary one. If your LO will drink cow's milk, she won't go without while you're gone.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
