My son said to me last night, with a very serious look on his face, "Mom, I need to talk to you about something important."

I wondered what it could be. Lately, all the talk has been about his birthday, which is coming up, so I figured it had something to do with that. Was he going to verify -- yet again -- that he would be getting a Wii U and LEGO City Undercover?

I was way off.

I said, OK, let’s sit down and talk.

He said, "Mom, a kid at school said he doesn't believe in God."

I was surprised he even brought this up. I thought we had covered all the bases. Our family accepts everyone for who they are and what they believe.

I told him, "Honey, that is fine. People have different beliefs, and we just accept them as they are, even if their beliefs are not the same as ours."

We go to a non-denominational Christian church.

I asked him how he responded to the boy, hoping he was not judgy. He told me he said, "OK" with a quizzical expression on his face.

Then he hit me with the hard question, "Are we right?"

For a moment I thought, whoa, this more difficult than telling him about the birds and the bees. (Yes, we have had the talk).

I thought for a moment and said, "It's not about being right or wrong. We believe in God and they don't, and that is just fine. Everyone is entitled to their own beliefs, and we respect that."

I think I got the message across.

Some day when he is older we will have the religion and politics talk, but at this age it's over his head.

How do you talk to your children about multiculturalism? Drop me some comments below or let me know @momsatwork on twitter.
