Quick: what do you use to mop up a hot tea spill when you're locked in a small room with your shirt pulled up, breast pump attached and on duty, and not a paper towel or napkin in sight?
A nursing bra pad, that's what.
If you don't know, these little beauties are filled with the same uber-absorbent material that's in diapers and maxi pads. They absord something like twenty times their weight in liquid.
Come to think of it, these things would make kick-ass cubicle coasters if they weren't so expensive!
