After a Pennsylvania restaurant made headlines this summer by banning children under age 6, the Yahoo! Shine website asked its readers: “Are kid-free restaurants a great idea or flat-out wrong?”Responders skipped right over the real question to list the many other places where children shouldn't be allowed. Movie theaters. Grocery stores. Airplanes. Disney World. That last one was a joke ... we think.In four days, the site got more than 20,000 comments. The biggest camps by far were the people who are fed up with small people who whine, cry, run around and poop their pants in public and the people whose own children never, ever do any of that.Lost in the din were the normal parents of normal children. All they ask is a little indulgence: Do we have to limit our dining options to Chuck E. Cheese? Do you really expect us to hire a baby sitter while we buy groceries? Can't you at least cut us some slack on the airplane thing?The no-kids-allowed movement, aka the Brat Ban, is gaining momentum, driven by quiet-seeking adults who want to prohibit children from everything from concerts to public transportation to Facebook. Demographics tell the story: The U.S. has more empty-nesters and more childless couples than ever before. One in five women choose not to have children.We understand why adults who want to enjoy a quiet restaurant meal object to parents who drop the leash and order a cocktail while their kids run screaming about the place. We understand about that cocktail, too.So we're happy to see the growing list of options for the child-averse: Adult swim. Theaters that have separate kids and no-kids screenings of the same movie. Quiet cars on the train. And yes, kid-free restaurants.Some Whole Foods stores have child-free shopping hours, with activities to keep the kids busy while the grown-ups forage for cage-free eggs. For a real getaway, there's leavethembehind.com, a website that specializes in kid-free vacation destinations.But sometimes there's no escape. On airplanes, for example. Every parent who's ever checked a stroller on the jetway has seen the looks of consternation from fellow passengers, even before the baby has made a peep. “Find a more child-friendly mode of travel,” one air traveler sniffed on the Shine post. Selfish, whiny, immature — no, we're not talking about the baby.Frequent-flying moms have learned to carry big packages of foam earplugs to share with seatmates; if the airlines were smart, they'd stock up, too. Individual passengers would be wise to bring their own, if they can't bear the sound of wailing.There are few things more unnerving than being trapped in a flying tube with a screaming infant. But babies have to go places, too.
