The Cass report explains how to affirm children is not a neutral act.
A small child does not know what sex is outside social stereotypes. There are actually experiments to show how little children think a doll has changed sex just by changing its clothes and accessories.
It’s takes time for children to understand they have a sex.
A boy child may present as more feminine than socially expected, or a girl child may seem more masculine in their interests but that is as far as it goes. Most will grow up perfectly normally. A few who are non-conforming may grow up to be homosexual.
Some parents are horrified by a feminine seeming boy or masculine seeming girl and the thought they might be gay. For them it be preferable to think their child is trans.
Some parents may have wanted a child of another sex.
Some parents may be caught up with fashionable gender and queer theories about artificial boundaries
Some ( looking at the USA) get to feel special through having a trans child.
There may be all sorts of reasons a small child says they are not the sex they are.
They may sense a parent prefers another sex. They might want to be like a sibling. They may be autistic and have been over literal in their interpretation of a stereotype they see around them.
Small children often pretend to be something they are not.
To say they are trans is most likely nudging coming from the parents for whatever reason.
Older children have all sorts of reasons for saying they are trans. Autism and needing to fit in coupled with black and white thinking, being in care, having been sexually abused, homophobia in their family, peer pressure to be part of a fashionable cult movement rather than an outcast.
Basically being a bit different from other boys and girls does not mean a child has a different gender identity hidden inside them, and if they think it does that idea has come from some sort of influence - dangerous one that can lead a child along an unfortunate pathway without necessarily curing what ever unease or incongruence they felt.
