My daughter did competitive cheer last year, and there was a fair amount of drama surrounding that, as you might imagine. I'd drop her off for her class, and then leave and go shop at the Costco next door the whole time! I refused to deal with any of it.
She has done ballet for several years, and she's in a level now where there are a fair amount of "dance moms" - although we are at the ballet school of a professional dance company, so there are no competitions, just theater performances. But that doesn't mean there's any less drama. Nutcracker tryouts are coming up, and you'd think it was a matter of life and death the way some of these moms are acting. I told my daughter, look, therse are open tryouts. Some kids from your dance school, some from other towns, other studios... just do your best and take whatever role they give you. But these other moms are so pushy - "Is your daughter trying out for Clara? What are you going to do if she has to be a reindeer or Mama Ginger child or something?" And I'm thinking... she's 9. She will be thrilled to dance on stage, just like she always is. I really don't want her to get the Clara role because these crazy women will descend on me like a pack of wolves. Ugh. (Time to find somewhere I can shop while she's at ballet! LOL)
