do diapers expire ?

i lost my pregnancy a couple months ago. i was 11 weeks, we had already bought a couple cases of diapers. i’m not sure what to do with them. i don’t know when i’ll get pregnant again, maybe within the next 2 years ? we weren’t even trying back then and probably won’t for awhile. should i keep the diapers ? im keeping all the other stuff that doesn’t expire. but im not sure if diapers “go bad” so i was thinking about donating them maybe.
