Another idea is if you are having to give some formula for "bottles so Mama can have some 'me' time" then mix a little of the breastmilk in with the formula so it gets used.
I'm always trying to find ways to use breastmilk up rather than discard it as I have had issues with supply with both my boys at one point or another. So any pumped milk is treated as liquid gold in our house!
