I think they should separate the sexes for sport earlier than most primary schools do, to be honest.
My daughter loved football from aged 4, but has really suffered from playing in mixed teams. A combination of extracurricular ‘mixed’ teams being in realityprediminantly make and school football being dominated by boys who are socialised to see it as a male sport that boys are better at.
It’s only now that she is 10 and playing in an all female team that she has really started to shine and is playing competitively for a local club.
Women and girls need their own sports.
