Not necessarily, but they shouldn't take their kids to a place like the Tate Members Room where it's an adult environment, there is nothing for the childrent to do. Can't they take them to Pizza Hut or Bella Pasta.
Sometimes it is nice to go up there for a quiet coffee with a friend and not to be confronted with screaming children running riot (sorry, I forget, they are expressing themselves) while mothers are expressing milk. Parents complain that people are not so tolerant of children, but there are those of us who choose not to have kids and have places like the Tate to get away from all that.
Pre-school kids don't want to go to modern art galleries, why not take them somewhere FUN?
The toffs have got the right idea: nannies and boarding school. Keep the kids out of everyone's hair...
(Given the recent trend towards throwing around accusations of bigotry at any poster whose posts contain sentiments that do not conform to a white, middle-class, liberal view of the world, may I point out that I am saying this with my tongue very firmly in my cheek?)
Are the kids any worse than the over-amorous couples who used to make a point of defying anyone to enter their personal space? If you couldn't get access to one of those tiny tables to Balance your funky giant tray with your overpriced tapas on, eating became a performance artform.
