"Just let the kid use the gender-neutral bathrooms. When he/she is a teen, if he is still convinced he is a girl, maybe then you can get into it with the school," said commenter EDM.
"This kid is going to have a hard enough life if he really is transsexual, why start fighting battles now, when he should just be blissfully ignorant"?
Commenter AlawJ said the story left a "negative impression of the parents."
"My rash view may be unfair, but I remember being that age and have helped raise 9 nieces and nephews. One wanted to be a firetruck and ran around making truck noises. Another one of the boys liked to play dress up with the girls," AlawJ wrote. "My fiance's little brother always wore dresses as well. But, at the end of the day, the parents are there to be the adults and make decisions for them.
"I also am a little weary when you read a story where the parents are filing lawsuits for their 6 year old child's rights."
