Different ethnicities and cultures / diversities for children?
My four year old DS came home from nursery today and said someone was 'brown and smelly', I was mortified and explained it was a horrible thing to say and quite upsetting. He said he didn't say it to this child just that two other boys had said it to him. I explained that there are lots of people on the planet and we may look different but we are the same. I then went on to say how Black Panther is 'brown' and said isn't he a superhero.
We live in a rural village which is predominantly white so he has not had chance to meet other people from different cultures. I'm sorry if I sound stupid / naive - I just want to make sure I get this right with him as I don't want him saying this again. I also want to use the correct terminology.
Is there another way to explain it to him?
Thank you.
