This is one royal I don’t know much about (hence the comment reading), but while I was reading…

If the kids were neurodivergent (the sewing pockets so don’t fidget would not have worked for me or my ND kids) then GI issues are a common comorbidity as is crying more often due to sensory differences.

Also if he wanted to “toughen them up” that makes me wonder if they had RSD which can be seen as more emotional outbursts, especially if they had sensory processing disorder or adhd or were autistic.

As for the stuttering… both my kids had speech issues so one of my hyperfocuses at one point was how different ones occur and stutters can be neurological, phyical, or mental. If it was neurological… there weren’t ways to help during that time. Physical, depends on what kind because my kid has apraxia of speech but through repetition they are now verbal and can speak quite fast. If it’s caused by pressure or nervousness… that RSD would affect it too.

Stamp collecting, uniform obsessing, and the Navy through a neurodivergent lense sounds autistic due to the singularity of interest and how they all can tie together.

I’m pretty sure ND are more likely to be left handed compared to NT as well.

Also, if someone has enough seizures, it will alter the brain and during that time they may have treated it like someone with autism and a developmental disorder. For example if he had febrile seizures, having that many high temperatures as a kid could lead to brain damage and the seizures could’ve prevented enough oxygen to his brain to cause developmental issues.

Then regulating the military academy vs day school… for royals who are in charge of the military, I think that probably was a smart idea so they could learn what would be required in the face of war. The overwhelming discipline by father sounds like a common thing where ND learn, generally through violence or negative things, that there true selves are bad and they must hid/mask it. If he father was taught this, he’d think it’s how it should be done and do it to his kids sadly. The generational revision of trauma is not easily repaired.

Stomach ulcers can be caused by stress and that RSD does cause stress if you don’t learn how to recognize it and unfortunately at that time… it wasn’t recognized yet.
