Kate Calvert, God bless her, suggests The Ivy or the Ritz, so that's got Liz Hurley and Zoe Ball sorted. For the rest of us, I'd suggest Julie's Wine Bar in Holland Park (it has a crëche on Sundays) or Lemonia, the child-friendly Greek restaurant in Primrose Hill. As for movies, there's no need to smuggle your newborn up your jumper, as I did with my son, Reuben, when he was three weeks old. The Ritzy in Brixton and the Clapham Picture House both offer screenings where babies are welcome.
