With most spouses you get the dialog option to ask them how the kids are, but there are a few, Vorstag is one, that never got that dialog recorded. Much to my dismay, as he is my current character's spouse. My previous character married Marcurio, and does have the option.
It's a shame, to the spouses with no dialog for it, it's like the kids don't exist. The children will refer to Pa or Ma though. Sophie tells me that Pa said he would take her fishing, and that with her help he should be able to catch one! lol
And yes, if you move one member of the family, they all go. Handy.
did he never here the exsperssion " we need to spend some time alone"

we need divorce!
oww i can just imagine it , it will be like when your getting wed you scream "WAIIIIT!! Stop THIS WEDDING !!"
and then the other one goes " *gasp* you b**** i hate you" and runs off and everybody else is grumbling embarrassingly
often thought it was all too much like katy perrys "hot and cold" opening scene - except without the wedding dress
also about wedding guests ? at my last wedding i found my daughter stone dead at the altar with my husband looking down going "ow , what a
shame" in his sarcastic snarl , andi n the front row i had two forsworn look like my witnesses , after the ceremony he looked round at me - husband i mean - and said " ow wait , you have kids,
dont you?!?" and thinking , "no , for some reason lucia is dead on the floor and nobody seems particularly concerned "
also i felt bad afterwards at home , husband settles down to his domestic duties as my slave , i felt like such a controlling dominant diva demanding he cooked me food at 2 am in the morning , fush do rah him off the bed and occasionally just punching him in the face . because i can .
marriage is comedy in skyrim , it is hilarious .
