In case the bespoke children's clothing stores and Bugaboos lining Bedford Ave haven't already tipped you off to the fact that the Williamsburg yupsters are breeding, here's an update: they're still all making tiny babies who will probably one day sport ironic facial hair at their private school proms. And since it's never too early to introduce your child to the simple pleasures of craft beer, they're bringing these babies to bars. But it turns out some drinking establishments are maybe not so thrilled with late-night toddler invasions, and DNAinfo reports they're establishing a kid-curfew.

The baby bar-curfew precedent was first set by bars in (surprise) Park Slope, where babies had reportedly been running rampant and ruining everyone else's drunken revelry with their tiny, germy hands and unyielding insistence on singing the Elmo's World theme song in the wrong key. Those bars started kicking kids out at 4 and 5 p.m., but since Williamsburg is edgy, neighborhood beer halls like Radegast and Spritzenhaus are setting way wilder curfews of 7 or 8 p.m.

"It's great for all of us, because what baby is going to stay up past 8 p.m.?" asks one Williamsburg mom whose babies may or may not be sneaking out after 10 to go clubbing. And she says she likes bringing her kids out to bars with her because they're so loud: "It's great because if your baby starts crying, nobody can hear it." Up next: Bushwick babies crowd surfing at Shea Stadium. Because nothing gets a crowd moving more than colicky shrieking on top of synthesizers.
