I appreciate you clarifying, I still think you're putting the emphasis on the wrong thing though - the ipad is a tool. What you might see as a "tantrum" might be an autistic meltdown because whatever it is they're looking at on the ipad is calming to them. It might not be. And their parent absolutely might not be invested in engaging the child, but they might also not know how (because they weren't engaged with and don't have a support system to teach them how), but my point is a kid using an ipad (or even being dependant on one) indicates nothing other than they're using an ipad, and we shouldn't be assuming anything about kids or parents based on their use, especially nowadays where everyone uses a phone or an ipad to do a large percentage of our daily tasks and interactions.

I can tell you from experience that a parent engaging in supposedly more beneficial things also doesn't indicate them being a good parent, they can be just as neglectful and even abusive, but because they seem "educated" people look the other way and assume they know what they're doing and couldn't possibly cause harm.

Sorry to ramble, I'm not trying to have a go at you, I just think it's important to frame this sort of thing correctly, otherwise we can't address the actual causes of the problems (like I mentioned before - a society where many people feel pressured to have kids because "it's the done thing" rather than because they actually want or are ready for them, and/or the system squeezing people to the point where they just don't have the time/energy/knowledge/support systems to be good parents).
