Has "family play" fallen back to the wayside? (Now with New OP)

Its obvious family play is ignored when pack after pack ignore babies toddlers and children... Packs like Vampires and ROM completely exclude these life stages and I'm not even saying they had to do much they could of simply had toddler vampires bite a teddy bear or have magic effects around them when mad or given kids a couple spells to practice like complete school work but instead made the decision to continue the single Sim adult game.
