Christmas morning is the one morning of the year that kids don't mind getting up early. Try to get them up at 6 a.m. on any other day of the year and you'll get wailing and gnashing of teeth. On Christmas morning, they're up at the latest. 

To be fair, I was just as bad when I was a kid. I think the earliest I remember trying to get my mom and dad up was 3 or 4. That didn't work out so well. Our family pretty much resigned itself to waking up around 5 on Christmas morning. That seems to be a manageable time for us. What about you?
