If shitty parent's don't care about well-being of their children, they could at least consider the cost of future medication, not to even mention likely worse performance in school and job market.
> While observing 422 children ages 3 to 5, a 2022 study led by Radesky found that mobile device use for calming — in other words, a digital pacifier — was associated with “decreased executive functioning and increased emotional reactivity.” (Executive function refers to memory and problem-solving skills needed for everyday life. Emotional reactivity refers to poor impulse control in response to stress, pain, and other negative feelings.)
ADHD is a type of executive function disorder.
I'll say it's misguided, as well as the root comment to which you're reaponding. The particular study soesnmt show causation, but there's a growing bidy of research that does (it's easy to find).
ADHD is an executive functioning disorder with mainly genetic causes, it is not something that you can parent a kid out of, or in to.
With lifestyle changes to you can manage it, or make it worse. But you don't cause it, or prevent it from happening from letting kids use tablets.
The current neurodevelopmental understanding sees the genetic component as latent tendency, with the environment as the trigger that can drive the manifestation of traits.
There is also something called "Attention Deficit Trait", which is case of ADHD like symptoms where the cause is not in genetics, but solely in environmental factors. While real ADHD is largely in genetics, I fully believe any individual can mess up their dopamine system by spending enough time browsing social media on their smartphone.
Most people who get ADHD diagnosis do have the condition (assuming proper diagnosis procedures were followed), but in a different environment it could probably be much less of an issue for many.
