How Many Kids and How Long?
Two important criteria to consider: How many children participate in the class? And how long does it last?
An hour-long program gives toddlers enough time to make transitions between the activities without getting bored or overstimulated. As for class size, smaller is definitely better. "Too many children diffuses the experience. If the class seems too crowded, it probably is," Lerner says.
"Though much depends upon the activity and the size of the space, more than a dozen kids with one parent per child is usually too much," adds Teitelman.
