Yes.
I really do believe that media - tv, film, YouTube mainly - is behind a lot of the confusion for many young people.
I've just found out that a child had transitioned from f to m in my child's school, name changed. Must have been in year 3 as they're now in y4. I know from a brief chat with the head that they school tries to tackle gender stereotypes. I know from a brief chat with a parent who told me that the parents went through 'it all' and the child is happier as a boy.
My first though was - how did the child know it's possible to do this? Because in many ways it's easier to be gender non conforming as a girl. My second thought was CBBC and YouTube.
If they're happy, in reality, what's in a name and clothes. Who cares. I just really hope the sex based protections are in place. The school's EA policy clearly defined sex v gender. The next school doesn't however I noticed, using gender only (first, middle school system, so next year.)
