My first child is a 5 yr old girl, and is very shy. What can I do to make her more confident and outgoing?

Be patient. Shyness is not necessarily a problem. Some people are quiet and reserved as they assess those around them and are outgoing when they want to be. Be patient. Let her become familiar with new people and surroundings without pushing her beyond her comfort level. You could also consider a play therapist to evaluate her and see what -if any -issues she has that might need addressing.
