<human>: My nearly 3 year-old goes to gymnastics with my wife.  Another mother in the class makes no secret of her hatred for her daughter.  I used "hatred" purposely, because she displays absolute disgust for her daughter through her words, tone, and body language.  

Yesterday, I witnessed a little of it.  The mothers/fathers were accompanying their kids in the lineup to do their routines for this winter showcase.  This mother made it clear she didn't want to accompany her daughter, was rolling her eyes when the daughter asked for mommy to come with her, and I didn't see this, but I was told the mother refused to accompany her daughter at one point.  

This mother has a mindframe that prohibits her from enjoying her daughter, and that's sad.  This daughter feels no love from her mother, at least during these classes, and that's unacceptable.  I feel as if I am actually witnessing a life being ruined because a girl is being taught that she is disgusting, unloved, a nuisance, etc.  I can't imagine it would be easy to unlearn that.

Could you distill the essence of the text into 1-3 sentences?
<bot>: In my son's class, another mother of a 3 year-old girl essentially hates her daughter, shows only disgust, to a troubling degree.  What to do?
