Sanders added that parents should heed the general advice regarding choking, especially for those 5 years and younger. "Children should never be unattended and they should never be within reach of any object that can fit through a choke tube, which is basically the cardboard tube of a toilet-paper roll," he said. This is particularly the case with objects not normally considered dangerous, such as children's toys that have batteries and other small parts, and various objects found in the kitchen or bathroom. "That's the best preventive strategy," he said.
