It's interesting because I see a lot of misinterpretation of normal, healthy milestones from people looking for proof of gender ideology.
For example, (collating a few 'my trans toddler' cases) cited their child as trans because of pulling off baby grows or bows, gravitating towards certain textures toys or clothes as proof their child is trans and therefore special. Wanting to imitate a different sex parent etc. Being rough and tumble (gross motor) or good at quiet craft (fine motor)
All very, very normal and marked by milestones that reflect the above and are actually used to measure whether there are any developmental concerns.
The vast, vast majority of children show these behaviours. We know them, look for them they're as old as the hills. The fact that people attribute them to being trans shows a misunderstanding of appropriate development and failing to recognise that whilst all children are unique and special, such behaviour is not an indication of anything other than timely development, which is common to most children.
Professionals don't label this behaviour or make children feel 'othered'. They use their knowledge to build on interests and skills to reach the next steps in development.
Attributing such behaviour to being trans strikes me as the opposite, very much wanting the child to 'stand still' in both interests and skills, which is not what is needed. Following children's interests means helping them build and grow, which is what it should look like and why we understand that the child is on a journey and not 'whole' at whichever age is convenient for arguing a toddler trans identity or puberty blockers etc.
I know trans children are really important to the movement to make it more palatable, but with years of experience in child development and education, would need more evidence than 'random adult with no experience says X so must be true' to change my mind.
What I have seen that's rather disquieting is previous studies being misrepresented to show genderist desires.
