"Man's Fight with MIL Over Daughter's Private Parts Raises Jerk Question"

A Reddit user shared his story about getting into a fight with his mother-in-law (MIL) over his daughter's personal hygiene. The user and his wife taught their daughter how to wipe correctly, but the MIL lacked such knowledge and didn't think her granddaughter had "real" parts down there. The MIL grew up in a strictly Christian household where sex education was not discussed, and she believed that a vagina only became functional after a girl's first period. The family has since resolved the situation and agreed to work towards better knowledge and communication going forward.
