I had a sim as a toddler play a bunchhhh with her IF doll and it aged to a kid no problem and was walking around with her and everything and then as a child I had her play with the chemistry set a lot...
Could i add a toddler sim to the family and spam play with and sing with then just trigger age transition twice to make IF a teen then use nraas' total annihilation to get rid of the kid? or would it delete the doll too?
