Just a quick story to tell you about what my 7 year old said to us today:
Son - "Aren't you happy God made us?"
Me - "Yes, I'm happy."
Son - "I'm happy, too."
Then we started talking about where would we be if God didn't make us. Son said we wouldn't even know we weren't here! We wouldn't be anywhere!
So sweet. I guess he was having a good day, and not, "the worst day of my life!"
My mom always said it's not quality time that's important, it's quantity! I wouldn't have had that moment if I wasn't around him enough (we were just cleaning up from dinner). Also, I think, any time with your kids is quality time. Just riding in the car, eating dinner, helping kids with their homework, putting them to bed, EVERYTHING can be quality time.
