This commandment gets a little tricky when you're talking to 4 and 7 year olds, but that doesn't mean it's not important....Commandment 7 - Do Not Commit Adultry.
We chose to focus our Family Time conversation on marriage. What is it? Why it's important? What does it mean? Who gets married? When we say this commandment instead of saying "Do not commit adultry" our kids say, "only love your husband or wife", for now, that works.
They really enjoyed talking about this and asking questions. Then we divided up the boys and the girls and allowed them to ask more questions (this was mainly for J). It wasn't anything too deep or difficult, but our purpose was just to make sure our kids know that they can talk to us about anything, there are no topics off limits and that we're always willing to listen.
Then we came back together as a family and since we didn't have time to watch our wedding video, the kids were the audience while Dan and I re-enacted our wedding day. We walked down the aisle, we said vows, explained what the pastor talked about and then of course, he kissed the bride b/c according to our kids the only people that kiss lips are people that are married (that's a great thought process and one we wouldn't mind them keeping!)
