If you don't have an answer to a child's question, it's OK to admit it. Tell younger children you will find out and let them know soon. Parents and older children can look for the answer together. Your local health department, Red Cross chapter, and medical association are good places to start. Show that you think the topic is important by discussing the assignment and reviewing the child's work.
Some children feel more comfortable asking questions of a medical professional.
Set family ground rules for your children. Be consistent in enforcing them. You might include rules for entertaining friends, going to parties at other's homes, curfews, drinking and driving, etc. Always let your own behavior serve as a good example. Working with Your Community PTAs often have the opportunity to work with other community organizations on HIV prevention programs.
