To be fair...
I have like 12 sets of bedding for my kids mattresses.  It started off bc I found them cheap and they're character sheets but then became a necessity as potty training and continued bed wetting  became a thing, even with the waterproof mattress cover.  My son (now 7) has gotten much better with bed time accidents but will still wet occasionally because he's such a heavy sleeper,  even when he's emptied his bladder before bed/ had minimal fluids leading up to bed time. My daughter is just starting her bedtime without pull ups adventure and I'm glad I have so many stupid sheets. 


Alternatively, for my older childs bed and my own, I only have like 4 different fitted sheets so I suppose this is all situational. 

To clarify,  the younger ones both have twin beds with a billion different bedding options,  oldest has a full with like 3 sets and I have a king with like 4 sets. And now the world knows more than they'd ever need to know about my bedding.

EDIT:  God awful spelling and grammar adjustments.

This is fair, though even then, if they don't wet the bed, do you still change them frequently,  or just as needed(weekly or some such)
