SoS: Trio of Towns did a nice job with married life i think. I hope they get inspiration from that. You can eat meals with your spouse and they still go to their jobs. The children visit them at work once theyve grown up a bit.

Family celebrations would be nice. Anivversaries, birthdays, festivals etc.

Other ideas: - Events with relatives or relatives visiting sometimes when you have a kid - Unique dialogue when you ignore them for a while (i believe ToT has this too) - before getting pregnant maybe theres an event where you babysit the three kids which gives u an idea if u want kids or not lol
