Should 'non-muslim' people go out of their way to teach their kids about muslim stuff ?

I don't think its necessary to explain everything muslim because they learn about it in school, but i think if that situation occurs you should explain what shes wearing why shes wearing it and answer any further questions asked. I also don't think it can be cled as offensive to come out of a small child because they do not understand. It is not said in malice.
