Pointer to a TODAY show video
When our kids were little I worried when I had to take long business trips because I feared that it wasn't good for them to have me gone for more than a few days. Now that they're grown, I know that those fears were silly, and I can see that there were many ways that those trips actually made me a better parent.
Those thoughts recently re-surfaced as I watched a short video from NBC's TODAY show recently. It highlighted the anchors' two-week separations from their families, espeically kids, while they were in South Korea covering the Olympics, and it showed their homecomings too.
Working parents whose jobs require them to travel will probably be able to relate to the stories they tell. (And older working parents will be able to relate to the differences between returning to babies and toddlers vs. teenagers :)
