Would a haakaa help build a stash?

Bri

I’m EBF my 14 week old son. And I haven’t had a ton of success with pumping (maybe 2oz at a time when I pump) but if been doing reading and people say a haakaa on your opposite breast while feeding will help build a stash. Has anyone has success with one? Would you recommend that?

Some background: my husband and I’s anniversary is coming up and we would love the day “away” from the kids. Just to have some alone time since we haven’t had any in almost a year. So I need to be able to pump or have a small stash for my mom to feed him for a day. Plus it would be nice to have some alone time and my husband feed him occasionally
