Then again, there are the tots who scream throughout the sermon in church because they know it will get the parent(s) to take them out.
...or maybe they are planing on selling the video of the wedding to American Funniest Video...
Having been childless, I surely know how you feel.
However, since having children, it has been my goal to include all of my family in every family event possible. It has become part of the culture. I attended a wedding where children were not welcome and it seemed funereal. To each his own I guess. Left up to me, I would promote an atmosphere of family everywhere possible throughout American culture, which includes children. As a parent, noone knows more than I do how inconvenient children can be at times. It's about taking the bad with the good and changing the paradigm of our culture. I think it's worth it in the end. But on some days I can sure see how some folks would disagree.
