如果是winding key 的话,如果是winding knob的话你给3岁以下的儿童试试?
it is the children's aptitudes to use a toy in accordance with its destination which justify the choice to intend them for the children of more or less then 3 years old; if this use can be gradual and start before three years to continue beyond, the toy has to be appropriate for the youngest children;
