Pumping & working tips?

Krista • Mama to a special snowflake, two frenchies & ttc#2 💗✨❄️👨‍👩‍👧🏩
I'm going back to work one month from today & am just trying to prepare my family & myself for the change. My daughter has been EBF on demand since day 1 (she's 7w today!),  we haven't introduced bottles yet. I've been pumping once a day for the last month just to get my freezer stock started. I'm looking for any tips or tricks to start introducing bottles, managing/using/organizing milk, & pumping tips while working. I'm a nightshift nurse working 3D a week & have a medela pump if those details help in any way. Thanks in advance!
