Bruce tries to figure out why his kids tend to fall asleep when they're under his cape, because it's been happening since Dick was Robin and twice with Jason could be a coincidence, but it's still happening by the time Damian arrives, so there has to be something there
It's the weight? They do like they weighted blankets, but that doesn't seem to be it
He's doing experiments, anything but asking, really-
And it's not like they'd actually tell him that the real reason it's not the cape itself, but the fact that to be covered by it they're being carried by him
They're being hold by their dad, and can hide into the little darkness that it makes, making a little warm, safe, comfortable place because of the man who's wearing the cape
Most of the kids cried upon realizing this, they hadn't felt like that in a long time, or ever before
But since then, it was always a nice thing for them, no matter how big they got
Dick had tried to forget about it when he fought with Bruce, but the first time he had to be carried around after patrol together again, it was still there
Jason had almost actually forgotten when he came back, and by the time he was in good terms with B, he definitely was too big for it, right? Wrong, when they got attacked with fear gas and he was the last to be able to get out of it, he found himself in that same old warm place
Tim felt wrong about it at first, not his place, like everything, he remainded himself, but as time went on, he found himself craving for it sometimes, to an embarassing point where Bruce will just start opening his cape to him every. Night. Not that Tim will say no to it. Bruce does that to him, it's almost a routine by now
Cass and Damian have always liked to hide in there for "surprise factor" but if they stay in for longer, and Bruce knows they'll doze off, it's not a problem either
It gets a bit hard when it happens at the same time though
It was one of the first things they all did when Bruce was back from the time stream, a nice way to process the idea that he was back with them-
