Rileigh undressing herself! (17 months old)

I went to go get Rileigh out of bed this morning and found her completely naked in her crib! She managed to unzip her pj's, take them, get her DIRTY diaper off and throw it all on the floor!!!! Thank goodness the dirty diaper ended sitting up and not all over my floor!!! I couldn't believe it, hopefully this is a one time thing and she forgets how she did it!!!!
