Breakfast with baby Jason was considerably more peaceful than breakfasts with adult Jason tended to be. Not that that was saying much. The bar for 'peaceful' breakfasts in the Wayne household was notoriously low.
Jason babbled at Alfred and treated the butler's patient attempts to get food into him as a hilarious game. Cass looked on and giggled, occasionally snapping a photo on her smartphone. Dick and Bruce became engrossed in a conversation about Zatanna and potential cures within seconds of sitting down, though Jason's high-pitched comments sidelined them every once in awhile.
At one point, something warm and sticky slapped against Bruce's cheek. He looked up, startled, and wiped at his face. His hands came away covered in oatmeal. Jay giggled mischievously.
Dick made a sound that was between a wheeze, a laugh, and a cough.
"You alright there, chum?" his father asked dryly, cleaning his face with a few deft movements.
"Ueehhyah," Dick said, his voice several pitches higher than normal. His face was firmly hidden in his hands. When he finally managed to look up, eyes tear-bright and dancing with mirth, the longsuffering look on Bruce's face nearly sent him into convulsions again. "Bless you, little wing," he gasped, pressing his forehead to the table.
Cass plucked Jason off Alfred's lap as soon as he had finished eating. "I will dress him," she announced with glee, disappearing back into the kitchen.
"She was… suspiciously happy about that," Dick observed as he buttered yet another slice of toast. Bruce hummed in agreement.
Cass reappeared in short order, a shit-eating grin on her face, and Bruce nearly had an aneurysm at the sight of the baby in her arms.
Jason was dressed in a hooded grey onesie with yellow accents on the cuffs and feet. Tiny little nubs pointed off the hood, childish imitations of Batman's cowl. A bright yellow pacifier, emblazoned with a black bat, rested in his mouth. The baby giggled, reaching out from Cassandra's arms for his father as she carried him back towards the table.
"Bat!" he said, the cry muffled by his pacifier.
Bruce took Jay from his daughter, eyeing the outfit with trepidation as Jason grabbed two tiny fistfuls of his shirt. "Cassandra," he said with a mildness he didn't feel. The outfit was heart-stoppingly adorable, but he'd never admit that. "What is this?"
Cass giggled and, tellingly, didn't answer.
Jason let the pacifier drop from his mouth. "Bat, daddy," he said, as if that explained it. He peered up with wide, earnest green eyes. "I a bat."
"And quite a charming bat you make, Master Jason," Alfred said, materializing from wherever he had disappeared to. Bruce jumped, startled, then cursed himself for being so distracted.
Alfred side-eyed him. "Your… guests have arrived, Master Wayne."
Bruce frowned, absently stooping to retrieve Jay's pacifier. "Guests? Plural? Hm. I don't suppose you'd like to warn me who exactly Zatanna brought with her, Alfred?"
The old butler's lips twitched the tiniest bit. "No, sir, I think I shall leave that a surprise."
Bruce sighed. "Well, let's go find out then."
