HELP!

DD keeps randomly taking her clothes off in the middle of the night/morning and peeing in her bed. We think she might be doing this when she is awake enough to realize that she has to pee and she knows she shouldn't go in her pants (pullup/'night time undies'). But I'm not 100% sure, she could just be doing it for shits and giggles.

I am so hesitant to change her over to a toddler bed, mostly b/c I imagine my nights being totally ruined and we have major 'baby' proofing to do before we can allow her access even to her own room when we might be sleeping. I don't understand why she just doesn't call us!?!
