Just for the record, I've had two screaming toddlers on my lap, now super 12 and 8 year olds. Smart, well-adjusted, good in school, polite. And believe it or not, they don't have TVs in their rooms, we limit their screen time and they, wait for it.... READ! They have conversations. Yes, now that they're older, they play video games, have mobile devices. But I never would have given a toddler something that would soak up their attention from the real world.
Call my post flamebait if you will, but I stand by my old-school ways (I'm not that old in fact) and believe human interactions and real-world experiences will always prove better than immitation alternatives.
