There was a new teacher who worked at DD's preschool during the summer before her regular job started in the Fall. She was young, did not have kids which we didn't mind. BEST teacher ever. Energertic, she was creative, gave us a lot of feedback, set boundaries with DD which helped us tremendously at home. The parents were pretty sad when it was time for her to leave. Personally, I would much rather have a new teacher with energy than someone who has been at the job for awhile and burnt out.
