They accommodate her as best they can. If she has specific sensory sensitivities, they won’t make her feel bad for them. If she’s overwhelmed in crowds, well, they understand and frankly are relieved to retreat home with her. They encourage any obsessions she has, so long as they’re not harmful to her or anyone else.
Kaneki loves interacting with her detailed imagination, and Touka is fascinated by the little rules and lists her daughter has.
If she doesn’t understand social norms, well, all the better in Touka’s opinion. Most social norms are foolish anyways.
Privately, Kaneki frets about a kid, who will already feel different due to her half-ghoul nature, having Asperger’s on top of that. Touka is worried, too, but a bit more practical. She emphasizes how special and unique Ichika is, and she and Kaneki both make sure Ichika understands that there is nothing to feel bad about.
