When do you toss your breastmilk ?!

If your LO doesn’t finish a bottle, how long do you let it sit before tossing it? I’ve been following to “up to 2 hrs” rule, but just curious. I have 40ml sitting here and kinda sad I’ll have to toss it this evening if she doesn’t finish it. My like had been slow since my good ole Aunt Flo came back in town 😠
