Emphasize that Pandora was well-loved by the two of you and that she had a very good quality of life before she died. Sometimes, a child will connect the death of pets with their own mortality, so you should reinforce the fact that death is not contagious. Have Andrea explain to you her interpretation of how Pandora died so that there will be no misconceptions about the death. It is better to explain the illness or accident in the simplest terms to enable the child to understand as much as her mind can comprehend. This will help her avoid frightening fantasies.
