I was diagnosed as autistic as an adult, I recognised traits in myself when my middle DD was diagnosed (as did her Paediatrician!). I am waiting assessment for adhd as well. I was born in the mid 80s, so this is in Primary in the late 80s, early 90s.

Not a care in the world if anyone got gravy on their hands. Every child would eat most of what was given to them every day.
My experience of this
Being told not to fuss and stop being silly and get on with it, and then as soon as I could going to the toilet and scrubbing my hands, feeling unclean for hours.

My experience of this
Hiding food I didnt like by smushing it as small as I could. Eating things I hated while gagging but not showing it. Being made to eat it while the dinner lady watched. Having a friend let me put some of my leftovers on her plate because hers was empty and that way it looked like we both left an "acceptable" amount. If I didn't eat it, I would get told off in front of everyone and the fear of being the centre of attention and everyone looking was greater than the need to not eat. I still have disordered eating now, and it took me till my 30s to realise I AM allowed to say no to foods I hate.

Children all wore school uniform. No adaptations allowed due to sensory issues, and none of my friends used to moan about the clothing causing them issues.
My experience of this**
Wearing and loving the feel of a pinafore dress until I was 8 or 9 but being bullied for it. Wearing knee high socks instead of uncomfortable tights in the winter and being bullied because long socks weren't cool. Wearing the cotton summer dresses as early in the year and as late in the year as I could, even when the other girls were wearing shorts or their school skirts because waistbands did not feel good. As I grew older- choosing to wear clothes that I blended in wearing, while spending my days stressed from how they felt and crying in the toilets when it got too much. And being told off for crying and not being happy.
I thought everyone felt uncomfortable in their own skin, in their clothes, with their food, with things touching them, that everyone second guessed themselves when they socialised, etc. Because we would be told off for not being compliant and told off for complaining and told off for being bullied and told to just get on with it when showing extreme emotion. So it all got internalised, I learnt I am too much when happy/ sad/ stressed and to hold it all inside...
*My experience now *
I do think the world is busier now too then the 80s and 90s which makes difficulties more obvious. I find shops louder, brighter, busier. Cars beep at you when you turn them on to drive them. Vans beep at you when they are reversing. Tannoys, especially since covid, are incredibly frequent, every 5 to 10 minutes there's an advert across the sound system in a shop. Tills talk to you. Shopping centres are full of lights and sounds and smells in the walking parts outside the shops. There are no quiet, calm places in city centres and retail parks to take a breather, even cafes are loud and bright and so on now. So I think society is becoming more overwhelming so childrens difficulties are becoming more evident as there's nowhere to hide. Dealing with an uncomfortable sock is far easier when everything else is comfortable.
