Usually diapered nowadays, maybe with a disposable changing sheet underneath for extra psychological wetting help. I just can't go if I fear about leaks, and my bladder capacity is pretty big.
I can remember about two instances where I didn't completely wake up, wet, and went back to sleep. I've never woken up wet without remembering wetting it. Would love to do the former more often, but even if I wake up it takes me a lot of mental effort to overcome my fear of leaks. I don't have a big problem standing up and wetting, though.
Been doing this for more than 6 years (although night-time wearing increased during the past year I guess), I wonder if I'll ever overcome my bladder shyness.
Other than diaper and pad, I usually wear socks and maybe a large t-shirt. During winter, I might wear a t-shirt with crotch snaps (bodysuit). Onesies are reserved for lying around on the sofa, though, as they are too hot to sleep in (heated waterbed).
I don't have a bedtime, and I usually don't sleep with a plushy. Sometimes I use a pacifier.
