Invite her school friends for playdates, not your work friends. The idea is to cultivate friendships with the kids she will be going to school with for the next several years. Ask your daughter who her friends are at school, or who she would like to invite for a playdate. If her school doesn't have a phone directory, get your daughter to exchange phone numbers with her friends. Call the mom and ask if they would like to meet you at McDonalds or something for a couple of hours to play.
