I am a parent of 2 young kids. Its supremely easier for me to just fuck off, give them screens, any screens and do my own thing, rather than get up and just fucking spend time with them, no screens just physical fun and games. Add mental dimensions to the games as much as you want, but they need to be manual, analog, electricity can be max in form of some physical buttons.
There are 2 types of parents among my peers - those who at least try to be a good parent, most of the time. Literally everybody knows how screens or junk food are damaging, there is no escaping to ignorance of this simple fact. The other type, they are a failure themselves - often obese themselves, empty shallow life without proper healthy passions, glued to their own phones all the time, evenings spent mainly in front of TVs. The type, when they die (and have the time to reflect before) are full of regrets and hate.
Without major exception, kids reflect very well into which category their parents fall into. My best childhood friend falls firmly into second category - whole family is obese (while he was multiple times a wrestling national gold medalist in his late teens and ripped). He is a heavy smoker, both cigarettes and pot, quiet mild alcoholic by his own admission (his wife too given how she gulps whole bottles of wine), no hobbies apart from gardening, no passions, just displays everywhere. Unsurprisingly, their kids are the same, just glued to screens, overweight. They never stood the chance, its always a sad experience to visit them.
All this while he thinks how good their live is compared to many people around them. Subconsciousness desperately ironing reality so they feel better about their lives, despite seeing facts every day from all directions how that ain't true. It keeps breaking my heart every time.
The prime responsibility of a parent towards their child is to do their utmost to raise a happy, well balanced individual who knows what they want in their lives and once adult (or even before) will just get up and go for it, whatever it is. I would personally add a pinch of self-discipline to make it all more probable, also a rare sight these days. Now how many parents around you are like this.
