“The nation’s pediatricians are warning parents today against putting children in shopping carts. ‘Parents are strongly encouraged to seek alternatives,’ says the American Academy of Pediatrics, which reports that shopping carts were involved in injuries to more than 24,000 children last year, mostly when a child fell out or a cart tipped over. But parents who have tried to pick up a couple things at the store while keeping their children from toppling the displays or playing hide-and-seek in the clothing racks may find the warning hard to accommodate.”
