Pros, cons of kids missing school for vacation

Bonnie Wach:

When my son, Rowan, was little, the idea that anything on his schedule would ever take priority over my expiring frequent-flier miles, or the opportunity to go on a vacation when the rest of the child-rearing hordes were in school, seemed to me like giving in.
It was like admitting I was one of Them – those overly involved, rule-abiding parents whose world revolved around PTA and soccer schedules, and crafting elaborate dioramas of Indian pueblos. After all, I reasoned, wasn’t the experience of seeing the Duomo in Florence or hiking Hawaii’s Na Pali Coast state park with your family as valuable as reading “The Very Hungry Caterpillar?”
Part of my nonchalance, I think, stemmed from the fact that when I was in school, summer vacation stretched for three languorous months, winter break for three weeks, and we had both a ski week and an Easter week.
