This isn't encouraging child abuse.  This IS child abuse, plain and simple.  As a parent, she needs to care for her child's well being, physical, mental and emotional.  Being fat will negatively impact all three of those, and what's worse, she KNOWS it.  She's doing it to prove a point, that "fat" shouldn't be a curse word.  Fuck you, lady, "fat" is absolutely a negative thing, and you're going to destroy your daughter's childhood.  If I could I'd call CPS.
