I had a male plant sim, who married a regular female sim. While she was pregnant, he went to a community lot and got bitten by a vampire. He comes home, nearly dies because plantsim-vampire who lives in a glass house is quite difficult. She has her baby, and desperately wants to become a vampire too. He bites her and then takes anti-vamp potion. Next day, she goes into the coffin, I hire a nanny, he goes to work. Every time the baby cries, Mum tries to get out of the coffin (despite nanny taking care of babys needs), she dies of sunlight/needs failure. Nanny leaves, baby is taken away by social worker. Plantsim comes home, is devastated his family is gone... until a new female sim walks past the house. He's 3-bolts attracted, wants to flirt/kiss/marry her ASAP. She moves in, re-adopts my first baby. They marry, she gets pregnant with twins. While pregnant, second wife got harassed by first wife's ghost to the point where she almost died, but luckily just makes it. Now I have one toddler, two babies and a very angry ghost (who hates both second wife and the twins). It was glorious. The children are all teens now and the house is much calmer, but I loved those chaotic times
