Adam, the youngest, always comes out to go to sleep now. It's a trend I started a few months ago (eternal thanks for suggesting it, Tylas

). If I myself try to sleep after lights out and haven't turned over the body to him, I feel panicky all over, I know it's him, and I really have no choice but to give in. He likes it because it's routine, it's his time, and it's comforting and feels safe to snuggle us to sleep. Even Little John, who used to take turns with him at "beddy-bye time" now has to share the body with Adam at best. It's possible littles naturally feel at home getting ready for or going to bed. It's the day winding down and outside the prime time when adult alters most want to be in the body (except when motivated by erotic impulses). I've had rare memories of my body doing Adam-like things in bed (humming, baby grunts as the body moves, hands/arms moving jerkily) in years past, long before I opened Pandora's box to my DID. I didn't know what was happening, it felt quite weird but purposeful, so I let it happen anyway. I'm sure now it was him.
I've found that since the littles started taking over at sleep, going to sleep and sleeping the night through is no longer a problem. I'm just not able to focus the mind on neverending ruminations about what went wrong at the job or things I haven't done. Used to be a terrible problem! Littles in the body in a safe bed serves to relax the body like nothing else. There's a reason for the phrase "sleeps like a baby." If you have some littles and you're not sleeping well, I highly recommend it!
Jack virtually always does the walking to/from work because he likes it and it assures him daily uninterrupted "talk time," though he's more and more tried to coax others out to take his place.
