I was surprised to read how many of the kids referred to them live in poverty: I supposed I'd imagined they would be the precursors to the blue-haired uni students
The single parent at my DCs' school whose child transitioned age 6 is on NMW. I strongly suspect that the non-resident-parent is extremely socially conservative and of the "no child of mine will dress like that". The child has a unisex name but on transition changed their surname to that of the resident parent.
My take is the NRP said "over my dead body", the RP was allowing the child to dress roughly how they wanted, but social media told the RP that they should allow a 6 year old who wanted to be the other sex, to believe they are the other sex, and a little knowledge (or social media) is a dangerous thing.
Scarily, the RP is now training to work with children full time.
The school has now told the class that the child IS the other sex, and my DCs are being forcefully reminded by me that this child is still their original sex, and no amount of change of clothes or toy preference can make them the other sex.
