Below are some photos that I have when my daughter was still taking ballet lessons to a dance place here in our area. She didn't like it too much so after several months, she decided that dancing wasn't for her. Her journey doesn't end there though. Her interest in music was shifted into playing an instrument which is really good because she loves it. Hubby and I supported her decision not to continue with the dance lessons because I couldn't be a good dance Mom anyway. I am not into make up and other cosmetics so I wouldn't really know how to dress up daughter during rehearsals.
I think her motivation was affected by the fact that she didn't like how they were being trained during the lessons. I think that if you want your kids to be good at ballet, they should take ballet lessons at this dance studio where teachers are professional and really knows what is best for your kids.
