Certainly not in kindergarten, certainly not before puberty. Who's so nosy about everybody else's family, anyway. I'm pretty sure if Heather has two mommies in real life this can be handled between members of the community without the school system becoming involved.
The only thing about this widely reported story that I do not understand is why these parents are leaving their child in this disgusting school.
I don't know why either. But it is good that they are willing to fight this issue.
