MINI GYM BUGS (3 years to 3 years 5 months) 45-minute class each week $89/4-week month. Our first step toward going “solo”….The Mini Gym Bug class begins preparation for the “solo” experience. Longer segments of structured activity are introduced. Parents provide guidance as needed but tend to play more of a background role as the child learns to follow and stay with the group. In this class we set up obstacle courses that allow the child to work with the instructor on a skill and then opportunities for them to practice on their own as they move through the different activities. The target teaching ratio for this class is 6:1.
