I'm glad you stuck up for the child, how awful of that mother! Do you know if the child was taken into protective custody or something?

I know what you mean about nothing being done about it sometimes when we report things. Sometimes that has happened to me too, either when I reported that I was being bullied, or when I reported that others were. Sometimes the people in charge may have been bullies at some time in their past and identify with the bully, rather than the bullied. Shame, but it happens, sigh....
