Plant Milk for Cow Milk

I've recently been making the switch to plant based milks recently, mainly because it just agrees with my stomach better. I will still buy cow milk for use in cooking, but because I use so little, it goes bad beforw I've used most of it.

I'm wondering if I can swap it for the plant milk so I don't have to waste it or go through the hassle of trying to plan around buying it for one recipe. Also when can I NOT swap plant for cow milk?
