Here's some contexts,

Lilith is Jodi's mother who is based off a porcelain doll. Mainly from Jessica Claus and lil bo peep.

Jodi's father was a scientist who created Lilith after his love fell in love with someone else, he killed her and Her created her using her blood. Her blood had her past memories and she was furious with him for killer her. But after he died suddenly, she realized that he was planning om creating a daughter. Lilith always wanted a child but could never had children, so she created Jodi (Real name Judith) using old material and her blood and the scientist blood.

It also kinda explains why Lilith looks so well put together but jodi was just a rag doll.
