I'd be kinda suprised, and a little worried. If it only happened once I'd pretty much ok with it, but if it started occuring more often I would worry a little, but as long as I only did it wearing diapers, I wouldn't worry too too much about it. I don't wear diapers to bed very often anyway, and I don't wet the bed so I would be some what suprised that I had peed my diaper. I can only think of one time that I think I peed my diaper while asleep but I'm not entirely sure. I had been wearing them all day and when I wear them, I pretty much pee as soon as I feel the urge, and by the end of the day I don't have to think about it too much. (I'm not kidding, I don't know why, but It's always been easy for me to just let go and pee.) I wore a diaper to bed and before I fell asleep, I peed some in the diaper and I fell asleep with it wet, but I remember then waking up in the morning and I thought it seemed more full than when I fell asleep. I'm not entirely sure because I didn't know for sure how full it was when i fell asleep and when I woke up, I still had to pee, so obviously, not everything ended up in the diaper while i slept (if any).
