Welcome to Plathville’s Kim Plath is staying out of the family’s main home because she finds it hard to live in the same house as Barry. Lydia confronted her about the fact that the three youngest daughters still need their mother in the house. In many ways, Lydia, who is a grown adult with a full-time job, has picked up a lot of the mother role in the house. Now that the family is discussing the fact that dad Barry will soon move out of the family’s main home, Lydia is considering moving in with him instead of staying with mom Kim and the younger siblings.
