Video: David Cameron's 'Home Alone moment' happens to the best of us David Cameron, his wife and three children had enjoyed an afternoon meal with two other families at The Plough in Cadsden, Bucks, when they took their eye off their eldest daughter Nancy. The family left in separate cars and only realised Nancy was missing when they pulled up at Chequers, two miles away. A Downing Street source Mr Cameron jumped straight back in the car and rushed back to collect his daughter from pub staff who were looking after her. Many parents have reacted sympathetically to the Prime Minister's predicament. Mumsnet's Katie O'Donovan said: "Whether you are Prime Minister, a teacher or a stay at home mum, being a parent is really busy and can be really chaotic. We all have stressful times with our kids when we lose them or forget about them temporarily, it's one of those things that happens to the best of us.
