NEW YORK (TheStreet) -- Just when you thought when you were gone, they pull you back in.
Yes, that's paraphrasing a classic line from The Godfather III uttered by Michael Corleone, but it could be used as easily and in similar anguish by parents across the U.S. when they find out their "grown-up" son or daughter is moving back home with them.
Three in 10 U.S. households are experiencing that, according to a 2012 study from Pew Research, The Boomerang Generation. Last year, Trulia released a survey showing 44% of jobless kids 18 to 34 live with their parents, and so do about 25% of kids with jobs.
To be fair, many households like the arrangement -- as long as junior picks up some of the household expenses tab. Pew reports that 48% of boomerang kids (which it defines as ages 25 to 34) help with the rent or the mortgage and 89% help with the household bills to some extent.
To make sure the living arrangement is a healthy one, emotionally and financially, the California Society of CPAs offers a list of "must haves" before parents agree to re-open their doors and restock the fridge for kids staggering back to the nest.
Here's the deal:
Teach your children well. Obviously, one big reason so many younger Americans head back to the roost is because they don't have a job -- or money. But some come back home because of poor money management skills, the CSCPA says. So get ahead of the problem in the first place by teaching your kids how to handle money, preferably when they are teenagers or even younger.
