DD goes to a school where a large percentage of children come from Polish families. (I'm not sure what percentage, but probably between 30-40%)
Over the last couple of years DH and I have noticed a "them and us" culture in the school. It's been bothering us for a while, but yesterday DD came home from school, excited that she'd had her school photo taken. I asked if a class photo taken, and she replied "No, but if I had, I would have been standing next to three Polish children, and you wouldn't have wanted that Mummy."
I am so
and
I haven't yet been able to address this with DD, but obviously will.
I have waited until I am calm to contact the school about my concern.
I work full time, so can't pop in, like I would like to do.
Should I address it to the class teacher, the deputy HT, with whom I've have a good relationship for years, as I've had several DC through the school, but it will be a bit "in one ear, out the other" or the new HT, who doesn't know me from Adam. Or phone the secretary, explain my concern, and know I won't actually be able to take a phone call if anyone calls me back.
I'm trying really hard not to go in "all guns blazing". But I'm so 
Please tell me if you think I'm over reacting.
