Or should I mind my own buisness?
We both have DC, in the same school year but different schools. A boy in my DC year has had major issues with an abusive father, the mother left him and started again enrolling him at school and not telling DF where he goes, I know the family quite well as we live close and our DC are friendly. She did start letting the DF have some contact but did not tell him the school he attends (to keep some distance) things turned nasty and they now have no contact and thankfully he doesn't know the address or school of the DC as he kept showing up at her parents bashing the door down etc.
For this reason she doesn't share photos of him in school uniform and has told the school not to include him in photos shared online, the school have the normal policy of not sharing photos unless of your own child, which everyone in the school seems to respect.
My SIL at a nearby school, regularly shares photos of her DD with others, it grates on me a bit as she ignores her own school who ask not to share online. She yesterday shared the class photo (of all 30 reception children) in their uniforms and with the school on the bottom. She also shared masses of sports day photos with other DC in the background without caring/knowing who she may be putting at risk.
WIBU to email the school and mention it?
