Are you returning back to work?
Pumping early is nice to
1. Build a freezer stash
2. Have a slight over supply to buffer the return to work dip
3. Have expressed milk to introduce a bottle before 5 weeks
4. Sort out all your pumping sizes/settings/pump early on
If you're not concerned with building a freezer stash or returning to work issues pumping can still help with engorgement discomfort
