There's a lot more pressure these days. And it starts from the moment kids start school. All kids must be above average! (The government really don't understand how this works!) which means from reception it's work work work - know your phonics, read, do maths, SATs, OFSTED, GCSEs, A levels, must get As in all subjects or you're a failure, and let the school down.
When I was at primary school it was very easy going, we did our topics, did art, PE, etc, there was no pressure or before and after school sessions in year 6 in the mad dash to get you up to scratch for SATs.
When my youngest (adhd and autistic) was at primary it was maths and English, maths and English. Only those, with one PE session a week, as SATs were the be all and end all. None of the promised sessions to help him were delivered,but I knew that once he reached year 6 they'd panic and up the pressure on him, so I took him out and home educated him.
I really struggled with the transition to secondary, so much so I was referred to a child psychologist (no idea what the result of that was - I told him what I thought he'd want to hear, rather than my actual feelings) and floundered badly.
I was diagnosed autistic at 45, after going through the diagnostic process with my youngest and doing all the questionnaires thinking "but I do that, that's me" I probably have adhd too, but haven't pursued a diagnosis.
My second is also autistic, but has learning disabilities, so when going through his diagnosis it didn't even occur to me that it was from me. I thought it was all from my ex's side of the family - lots of, what was then Asperger's, diagnosed or apparent in my kids cousins.
Obviously my son would have been sent to a home back in the day, not seen out and about in public.
My brother is sadly dead, but he definitely had adhd, noticeable from a young age. He was just a "naughty boy" though, and a fidget, and hyperactive. Nothing wrong with him at all, oh no.
I'm happy to now have a label of autistic, rather than the labels I grew up with - stupid, slow, unorganised, messy, dreamer. I'm glad my youngest son doesn't have to go through life wondering why he's different and being labelled like that.
