Living far longer than any normal human being allows you quite a lot of time to collect knowledge from many corners of the globe. He knows the human body practically inside and out by now; he can speak fluently in over 24 languages. He knows how to tie knots professionally like the best sailors; he has learned how to write in a code so unique that literally nobody else on Earth would be able to crack it without a century or two of free time to crack it.
However, his impressive, extensive knowledge over all things medical and scientific unfortunately could not save him at the moment.
He fearlessly met the wide blue eyes staring back at him expectantly, waiting for him to do something clever.
He could hear Abigail failing the stifle her giggles out in the hallway, occasionally peeking back into the room only to begin again as soon as she saw them.
'Them' being her husband and adopted son currently having the staring contest of the century.
Nearly a century of existence had not prepared Henry for parenthood at all, so figuring out what it was Abraham wanted was next to impossible; especially when since he couldn't eloquently explain exactly what he wanted either.
He raised an eyebrow in question at his son, who had climbed up onto his lap ten minutes ago and had refused to budge, despite both of his parents best efforts. "Did you need something, Abe?" he asked slowly, blinking and resisting the urge to groan when the toddler only shifted slightly in his lap.
"I have some research to compile, Abe," he explained quietly, shooting a begging look toward the door, but Abby had disappeared; he could still hear her laughing somewhere down the hall. "Why don't you go play with mum until I'm done?"
Abe simply stared at him, wide blue eyes – so like Abby's, even though he wasn't actually her son – fixed intently on him.
Henry bit his lip a bit. His notes were still in a haphazard mess on the desk he'd been working at; maybe…
"How about you help daddy sort some things out?" he suggested.
Abe's eyes lit up almost immediately. "Da!" he yelped in agreement, latching onto his father's chest in glee.
Henry gave a fond sigh, hugging the child to him with both arms.
"Yes, yes, I know the full list of known diseases is a very exciting thing; trust me, I've read it myself. Very interesting. I should read it to you sometime; you'd love hearing about asthma, bronchitis, mumps…"
He might not know much about kids – not even his own kid – but it seemed his kid didn't have normal interests.
He supposed it just ran in the family.
A/N: Someone was asking for more toddler!Abe. Thus, more toddler!Abe. Enjoy!
