I can't deny, it warms my heart to see this. Especially since an hour before he'd asked to use the iPad to watch something on YouTube, and I'd said no, so then he amused himself first by building electric circuits with a kit from his uncle and then by reading.
I can't help thinking that such activities are better than videos and app games... but at the same time, I wonder how much of this is really true and how much is curmudgeonly-ness. Also, snobbery. And there's a bit of hypocrisy mixed in too: I do let the kids use the iPad when it suits me to be left alone, sometimes. And I like veg out in front of the TV. Plus I'm conflicted over my rules:
leave your brother alone and find something to do by yourself when the other is reading, but
you have to share it together when it comes to iPad usage.
Still, it warms my heart to see my kids reading.
