What do you think? Donating milk to nicu babies.

I have oversupply & have been accepted to be a milk donor to my local hospital for the NICU babies. Should I do it? What do the premie parents think of this? Would you appreciate having donor milk for a premie?

UPDATE: Thank you ladies for the advice! I will definitely be donating :) my goal is at least 100 ounces a month & at least 1000 ounces total before I stop.
