Some kids have a tap of inexhaustible energy, constantly flitting from one activity to another. If you walk into a preschool and observe that the facility doesn't give him an opportunity to run around, it's best to move on. Some kids can jump into a new school and hit the ground with both feet running - transition is not an issue. Others hold back and size up a situation before plunging ahead. In the latter case, it's critical to find a program where the teachers make an effort to involve them, while not pushing them intensely to adjust on the first day.
Some kids simply take longer to make the transition.
Many young children crave commotion, and the opportunities that busy preschools offer. Others have a lower tolerance for noise and commotion, and become easily overwhelmed by a chaotic playroom. Some kids crave schedules, and must have one in place every day. They eat, sleep and conduct their play activities by the book, day in and day out like highly organized individuals. Most preschools follow a daily schedule that children craving regularity will find comforting.
