Diapers & Diaper Changing: Toddler, Princess

18 Month Old Will Not Stop Taking Clothes and Diapers Off

I am a mother of 18 month old triplets and one of them will not stop taking her clothes off and diaper too. She does it when no one is looking. I have tried all different types of outfits from one piece to sleepers, she seems to master them all. Does anyone have any advice, twice this week I have had to clean up a very dirty crib in the middle of the night, if you know what I mean. She's a sneak, please help!
