So I was inspired by someone on Facebook who is re watching earlier seasons.
My On Demand starts in season 2.
The first ep, they are in Lehi and all the kids are now going to public schools.
Except Mariah. Meri said on camera that Mariah just prefers her private school. A later shot of Mariah, all calm and smug and sanctimonious coming home from her $$$ private school, confirms this.
A special snowflake from the start. The other kids had no choice.
