22 month old stripping constantly


My almost 2 year old takes her clothes and diaper off every chance she gets. Every single night she strips naked in her crib and I end up washing her bedding at least once a day, twice if she does it during her nap. She strips and then covers herself in her blankets or puts them between her legs to soak up her pee. She’ll do it even if her diaper is dry so it’s not a potty training sign. She’ll do it in the middle of the day and then stop once I catch her and tell her to stop, but there’s no rhyme or reason for it. I’ve tried all the tricks, backwards diaper backwards footless pajama etc etc. Any insight into WHY she’s doing this or other creative ways to get her to stop? My water bill is going to be outrageous this month 😩
