Apparently eldest looks back at his 15-16yo phase and cringes and so is trying very hard to accelerate the younger two through it as quickly as possible so they don't stay "cringe" as long as he thinks he did
seeing the ridiculous of older siblings is why the younger are so talented!
I am the fourth in line ;D
But yes, it isn't just the brain development, but I think it also has to be somewhat of a decision to start improving. It can't be forced by others too much.
(all of which some people intrinsically tie to their identity and thus feel "attacked" and lash out violently if anyone dares to possibly hint at criticising)
Yes. They are in areas that are personal and people feel "right" in based on their experience, but there isn't a clear answer as to what is actually right or wrong - it is all opinion. Maths has less variance in this, as an equation works or doesn't.
Then I was left wondering how anyone learned or learned how to deal with anything if you were never allowed to talk about this stuff you just apparently needed to magically know about XD
Everything I know is magic at least!
Culture and environment teach it too, even if not talked about. Then, that identity is built on it and makes it hard to talk about, break, change etc...
Sometimes even the decision isn't enough. At 7 my eldest very desperately wanted to be able to read. They all had Reading Eggs books that they were working through, middle child had pretty much "cracked the code" at 5, but eldest struggled. He cried every time we worked on English as no matter what or how much he tried, his brain simply refused to accept or understand certain blends.
Shortly after turning 8 he marathoned through the Artemis Fowl box set after not being able to read the bigger Dr Seuss books, apparently his brain decided it now just got the things it was refusing before.
Man people are messy.
