My DD is 14 - we have been involved with CAHMS since she was 18 months old.
I have pretty much every parenting book going. I tried every strategy anyone suggested.
Family history has diagnosed ND going back generations - and rather a lot of suspected but not formally diagnosed.
We could not medicate DD for years because of a growth problem - so we waited till she was past puberty and growth spurts before seeking a formal diagnosis (it was first discussed by professionals when she was 5) and choosing to medicate.
DD has also been referred for psychotherapy to help support her - it's not just meds.
She masks well at school and out - she can sit in a formal restaurant no problem at all, but we all pay the price later - mainly her. So yes, I have let her have screens because it makes everything more pleasant for everyone - and guess what, I'm often exhausted from normal life, parenting DD and my own neuro-diversity and need to not be constantly telling my child not to do x, y or z or arguing with her.
Medication was very much not the first port of call but the last. Having seen the results so far, I now have immense guilt over how much easier her life might have been had I pursued that route earlier (and sod the potential inches that might have been lost).
What is incredibly hard for parents of ND kids is that you know that half the world are thinking you are either a lazy parent, or that you just rock up to the clinic suggesting ADHD and they just hand you an Rx for amphetamines.
The reality is that it's huge amounts of paper work, questionnaires, reports, interviews, medical examinations etc to get the diagnosis. When you have had to jump through all those hoops, have your parenting put under the microscope, it's actually a bit of a kick in the teeth to then have people with almost zero knowledge of the condition tell you how everyone is 'buying' their child a diagnosis, or sticking pills into their child to avoid having to take responsibility for being a parent.
Funnily enough, yes, lots of us are on forums - probably because we have worries, we are hoping to find answers, new strategies, or just other people who know what the reality is of watching your child struggle in a world designed for NT brains.
I remember when she was 4, and we were really struggling with her extreme demand avoidance, that a friend told me that she found if she just got down and said to her child 'Jane, we don't do that' that it worked and had I tried it? Hahahaha...
I asked what she would do if Jane didn't comply and if no consequence worked. Would she shout at her? Beat her? It's extremely easy to be a great parent if you have a child for whom normal rules work - not so easy when you have one for whom rewards and consequences are of zero interest.
It's also worth remembering that ADHD has one of the highest rates of heritability of any neurodiversity - around 74% - so it is quite likely that a lot of parents of children with ADHD have it themselves and will find it a much harder challenge parenting that an NT parent would.
