Oh well, RIP to Mario. (I think you accidently had him propose, that sort of makes the one proposed to take the last name. You can get back the Dreamweaver name by renaming the Sims at City Hall during the day.)
And Cinnamon looks like she'll become old and your dynasty will fail because you couldn't get a man to marry in. Ugh. I know I sound pessimistic, but it seems good guys are hard to find, especially when you're a working girl, that's why I try to marry my Sim women as soon as they age up; also, avoid newspaper boys like the plaque, the two kids I was going to have Chocolate marry became too old for her when she was a teen! Urk! Thank goodness for Youssef Nagi! He may be a flirt and not throw any wishes, but he is a good man.
Anyways, it seems my Dynasty's turning into a mirror clone of yours - we now have there generations of women in the family(Eggnog, Chocolate, and now Sugar and Honey) and YES, Sugar and Honey are Chocolate's twin daughters, just like your second and third generations! I admit to playing kids music a bit but I only did it for this generation and will prevent that in the future. I just wanted to have a twin girl to work on the Handiness Skill so I can hold off Handiness for a generation or two.
The thing is I made it a rule that whatever gender was wished for by the immortal would be the gender of the baby, but "Have a Girl" was in Eggnog's wish and also Chocolate's. I wanted Youssef to wish for a boy so I could get some points for a Mid-Life Crisis for him, but he didn't throw the wish for anything even after the baby bump! Weird...
Good luck on your story and have a safe holiday season, Pam.
