A few years ago, author Rebecca Hagelin appeared on Fox News' “O'Reilly Factor” to promote her first parenting book, “Home Invasion.” During the interview, an incredulous Mr. O'Reilly challenged Mrs. Hagelin, asking how she reacts to teens who rebel against standards in the home about media.

Mrs. Hagelin calmly explained that when children and teens understand their parents' standards and values, they tend not to rebel much - or at least, that's been her experience. Mr. O'Reilly summarized, “Well, then, you're just lucky, that's all.”

I've no doubt that Mrs. Hagelin is lucky, in the way that we all feel blessed with the embarrassment of riches that parenthood brings. But it wasn't luck that created a household in which she and her husband could expect that their children follow guidelines about media consumption; it was skill.

Parenting skills seem to have gone the way of the hula hoop. Perhaps it's the result of our increasingly transient society, where families move from state to state for jobs, better weather and quality of life, leaving behind networks of extended family from whom to learn the tricks of the trade.

Or maybe it's the growing sense of defensiveness about parenting decisions that makes it socially taboo to question or comment on the choices of another mom or dad - choices that may affect our own children in the process.

You can easily learn how to make “green parenting” choices and serve organic snacks after school, but the advice on asserting authority in the home while forging close family ties tends to defy common sense.

Thankfully, Mrs. Hagelin is back with a primer that shares what she knows about being a parent. In her new book, “30 Ways in 30 Days to Save Your Family,” Mrs. Hagelin offers common-sense insight into the daily struggles, successes and skills that ought to be instinctive to most moms and dads, but which our culture has rendered unusual.
