Preschool Moms, any suggestions?

My 2 1/2 year old son will be starting preschool Monday at Children's Courtyard. I'm a little nervous. He's never been in daycare before and he's attached to a pacifier. Will I look "panicky" if I pop up at his daycare everyday for an entire week, just to check up on him? Without him spotting me, of course. How will I be perceived by the teacher and director? I've heard the teacher's usually advise parents to leave the pacifier at home. I'd probably bag it and hand it to the teacher just in case he has a meltdown (I guarantee one). Please help.
