Basically that. My sil thinks the opposite. We have similar aged children and when she heard my dd's who is only 4 btw, best friend in Montessori is a boy she was shocked,and when I told her that Ballet ,rugby or karate classes were offered to my ds ,she gasped Ballet for boys!!! Hes not doing Ballet but the fact that Ballet classes were even available for him was outrageous.
Really thought people didn't think like this anymore.
She has a ds and a dd. Wonder what will happen if god forbid her dd wants to play Rugby
