I just want them to get along

Bruce wanted to know why these types of problems always happened to him and his family. When he first donned the cape and cowl he never expected to be up against such unusual and bizarre circumstances, such as fatherhood… but having his 10 year old turned into a baby is a bit strange too. It's shocking to see Damian so small, with chubby little hands and cheeks, he looks almost innocent. That illusion was quickly swept away by the baby's perpetual fussiness, constant low level whining and a stubborn wrinkle in his brow Bruce notes Damian still has even at his proper age.

"You're holding him wrong B, you got to support his head." Jason comments from the other side of the room, sounding like every word was a challenge. "He's your kid, not a bomb; you need to stop acting like you're about to throw him at some supervillain."

"I have experience holding children Jason, this should be no different." Bruce warned as Damian squirmed and continued to cry in his arms. He made a face, usually the children he dealt with weren't this difficult. Jason sighed and stalked over to them.

"Well first off, no matter what you say, it's always different with your own kid; it's always more important. Second, he is your son so is it really any surprise he's a contrary pain in the ass?" Jay throws out, not even asking before scooping the baby out of his arms. He clicks his tongue at Damian and bounces him gently until Damian finally begins to settle down. Jason smirks and makes little faces as he lets Dami grab at his fingers.

"You're good at that," Bruce observes, taking in every detail for further study from Jay's posture and hold to the soft, contented smile on his face. Jason shrugs self-consciously.

"Kids are easy, they're small and they don't know anything. You just need to make them comfortable and safe. There are tons of little kids hanging 'round the Alley and you have to make sure they were quiet and out of the way or you wouldn't see them again." He replies lightly but his eyes have sharpened and Bruce doubts that Jay will be giving up Damian any time soon. "So off you go, old man."

"Excuse me?"

"You don't want to be here, being domestic while Wing and the Replacement are running around investigating whatever the hell happened to the Brat. We both know you never cared for the whole parenting thing and you like it even less when the kids can't even take care of themselves." Jason answered, his voice harsh and bitter but his face was soft as he continued bouncing the baby. "So go put on your suit and go punch someone in the face, it's what you enjoy and what you're good at. I'll keep the little Demon safe while you're gone."

"Jason," Bruce says quietly, feeling like he's gone back in time and Jason is 15 again, yelling at him for not bothering to understand the boy's problems. The more time that passes, the more he realizes that nothing had really changed when Jason came back to life. They still had the same troubles and arguments just with much higher stakes. "It's not like that," he says weakly which earns him an eyeroll.

"It never is, now get. I think Alfie pulled out your old crib and it's about time for baby D to catch some Z's." He turns his back to Bruce and it's like Jason is leaving his life once more, telling him that it's time to step up once and for all.

"You're right," Bruce says suddenly, reaching out to grab Jason's arm. "This isn't easy for me, it never has been and I know I've made more mistakes than not but I will never stop trying and I will not ever walk away from you, from any of you." He squeezed Jay's arm. "He is my son, I want to be there for... like I wasn't there for you. Please, show me what I need to do, tell me how to help and I will do it." He glances down at the baby before looking back up and holding Jason's gaze, trying to convey the feelings he hates to acknowledge.

"Uh," Jason replied intelligently, looking for words. "Let's go upstairs, I'll show you how to hold him, put him in the crib and then," he pauses, "maybe we can talk, like for real this time." Bruce smiles at that and manages to coax a small smirk from Jay in return. It's a step, a small step, but it's something.

"Alright, hand him over. I never got this chance when Damian really was this age, I might as well try and make up for it now. It's not every day we get second chances." Jay snorts at this but very gently hands Damian over, rearranging Bruce's arms until the baby is relaxed in his father's arms.

"This family is so weird," the boy mutters as he shakes his head.

Prompt for this one was "Jason and Bruce bond over a turned-into-a-baby Damian" which I think I accomplished, making I cute but also somewhat within character. I don't know, I hope you like it.
