Kaito was poring over a fake birth certificate when the doorbell rang. He abandoned the paper and drying ink and started for the door -- then skidded to a stop, turned on his heels, and went to pick up the baby currently crawling on the living room carpet. The baby, seeing him, of course did his squirmy little best to disappear under the coffee table. The bell rang again as Kaito was attempting to extricate him without bringing the table along.

"Coming!" he called out, swinging the child up in his arms. Peals of baby laughter rose. Kaito couldn't help laughing along as he jogged to the front door.

"Well, I see you're having fun," Conan commented dryly when he opened it.

Kaito grinned and waved him in, closing the door behind him. "I'm so proud. He's a budding escape artist."

...

"He's going to be a handful. I don't feel so bad anymore about letting you go," Conan said, wry and amused. "Looks like he'll keep you too busy to steal so much as a minute for yourself."

Kaito's sidelong glare only made him smirk wider.
