Thank you for viewing. Explains the basics of illnesses and injuries, with a consultation guide chart. Latest Illness & Home Care New Encyclopedia Target age: 0-6 years old I purchased this when I was concerned about my child's health and only looked at it once. It has been kept in a book stand. There is almost no sign of use, but it has a slight curve because it was kept in a stand. I think it will flatten out if you put it on a flat surface, but please consider this when purchasing.
