Speak for yourself. I personally work with a number of goyim who I consider friends. I have gone to get togethers at a mom-Jews house and they ordered in triple wrapped food from a place acceptable to my family, we had a table just for our food and the entire party was served on plastic ware. I am not of the belief that I am on a higher level then a fellow Jew OR fellow human. We are all on this earth together.
Back to the OP. as long as you supervise your child you should be fine! Gl
