First it was smokers, now it is children. A Berlin caf has excited debate by establishing a no-child section. For a nation with a low birth rate that is trying to encourage its citizens to have more babies, such an anti-child policy is cause for concern.

In the middle of one of the most child-friendly neighborhoods in Berlin, one caf is bucking the trend. In what appears to be a first for the German capital, the Caf Niesen in Prenzlauer Berg has established a child-free zone on its own premises.

The caf, which Christine Wick has run since 2005, is located in a cul-de-sac near a park and is opposite a petting zoo, which makes it the perfect place for parents to grab a drink or snack together with their offspring. But as Wick told the Berlin tabloid B.Z.: "My regulars were not finding it peaceful."

"Recently there were more and more parents with children, which is why we rented a premises to serve as a special, separate area for adults only," Wick, who has a 9-year-old son herself, told the mass circulation Bild.
