Sara wanted to buy a "Dodo" mechanical doll for her three years old niece, Nana. "Dodo" toys were sold at much reduced prises as a sale promotion for two weeks in the Metro supermarket. Sara selected a doll, bearing a "Dodo" label from the display rack and took it to the cashier to whom she wanted it for her three years old niece. The cashier told her that "Dodo" is suitable for her three years old niece. Three days later Nana complained of stomach discomfort and was taken to the hospital by her parents. It was found that Nana has contracted a gastric ailment, as result of sucking the doll, whose paint contained celluloid. It is proven that quantity of celluloid in the doll would not affect most children. Advise Sara and Nana parent.
