I find this really sad.
Could it be linked to internalised parental sexism attitudes?
I do remember going to toddler singing groups with my two and being quite surprised it was mostly girls.
And I also remember one day where most of the girls were very scared of Dinosaurs, which happened to be the theme. (I bloody loved dinosaurs from an early age.)
