First-time attendees are sometimes a little uneasy in a new environment. You can often make them feel more welcome by personally introducing them to several of the other children before you start, especially if if can point out specific things they have in common with the other children: same age, school, interests or hobbies. Of course, this means that you have to ask the child to tell you some things about himself. Reciprocate by telling him some things about you.
