I still have some time before going to bed and it's still May 10th in my time zone, so might as well contribute to the EH day with some family headcanons
This is a thread
because I don't know how to fit my ideas within Twitter characters limit



By the way, they aren't an AU. Just canon divergence.
I've said multiple times that I think that both Eren and Hisu are terrible cooks, with Eren being just slightly better for half-listening to Mikasa. However, as soon as he realized that he would become a father, he begged Mikasa to teach him again how to cook.
Yes, Eren doesn't really needs to know how to cook as the Queen's husband. But neither of them is comfortable living at the castle and being served all the time. Eren feels satisfaction by being able to cook for his wife and his children, specially for those late night snacks.
Historia is the one that reads bedtime stories. If Eren tries to do it, he might as well fall asleep before their children.
Hisu really encourages her kids to learn how to ride horses. Eren, low-key, teaches them self-defense and passes on Annie's techniques to them.
Eren and Historia are the kind of parents that allowed their first born to sleep between them until they felt like they wanted a second child. So probably less than three years.
Historia is the one pushing for her kids to receive the best education as possible. She's loving, yet she's strict on them. That's why Eren is seem as the fun parent. As serious as he looks, he's always down to play with their children.
Historia is the one that is most physical with her affection. She's always hugging and kissing her children. Eren, instead, do acts of service to them: he builds they toys they play with, he cooks for them, he carries them to bed.
As a family, they truly love strolling around town.
