If you have a moment, read this lead story in Time Magazine. Are you a helicopter parent? I definitely have some helicopter tendencies.
Also, I found this general societal comment interesting:
Some of the hovering is driven by memory and demography. This generation of parents, born after 1964, waited longer to marry and had fewer children. Families are among the smallest in history, which means our genetic eggs are in fewer baskets and we guard them all the more zealously.
