Wow! I give you so much credit but that is definetly too many li-ttle dancers for one dance class.
I am guessing that you do not even have a assistant dance teacher
for this dance class. I am not sure that it would be helping sin-ce there are so many little dancers.
That class should definetly be created into two or three differe-nt little dance classes. I really would be speaking to the dance studio owner at this pointe. It sounds like she is pretty diffic-ult to communicate. I hope that she listens to you because somet-hing needs to be done with this dance class.
