they said they felt like a female from age 4, which does not really fit with AGP. This a mystery.
Its the common narrative construct.
Childen dont 'feel like the opposite sex' at this age & stage of development. Child psychology has long established understanding of how children develop language & classification.
The process is demonstrated really clearly in this important article by Dr Katie Alcock (Lancaster University developmental psychology) based on the speech she gave in April 2019 at a meeting organised by members of For Women Lancashire entitled 'Gender Identity: Safeguarding Children and Young People'
'Young children, reality, sex and gender'

I read Twitter a lot and I’ve come across this statement — that children who are “trans” knew they had a “gender identity” different to their biological sex when they were very young, 3, 4 years old — quite a lot.
For example, this tweet by Mermaids¹, a lobby group that advises families who think their child is trans (and only ever says YES your child IS trans), and trains schools (recently refusing to engage with a biology graduate school governor), quotes a study by psychologists at the University of Washington:
"Trans kids as young as 3 understand their gender identity. Study"
So, what exactly do these type of studies and quotes mean by “gender”, “sex”, “identity” etc.? What have psychologists found out about children’s developing knowledge of sex and gender?
Well, this research has been going on for a loooong time. All the studies I’m going to talk about are really robust — well replicated — this means that lots of researchers have found the same thing time and time again. We have known about some related aspects of children’s thinking since the 1920s or earlier and some of the main, older studies in this area are from the 1960s. This is not a flash in the pan.

... it takes children some time to work out both whether they themselves are a girl or a boy, and that both they and others cannot change sex. Working out which they are themselves happens earlier, and is based in all the studies that have been done on physical appearance and stereotypes. (continues)
... Making generalisations is a very useful skill for a baby or child — if they couldn’t make generalisations, they would never be able to work out that a new cat they saw was in fact a cat, or a new apple was just as good to eat as the last one, or a new car is likely also to go places. Children can work out at a very young age that there are men and women, boys and girls, in the world — it’s probably quite useful for them to work this out in the general scheme of things².
So when they see all the girls at nursery wearing pink and having long hair, well, that’s what girls do! And they also realise, from what people are saying, and from how their parents dress them, what toys they are given, and what toys other children who look like them (same clothes, same hair) what they are supposed to like and do based on what sex they are."(continues)
