A few years back when my kids were toddlers I’d rather naively give them my phone with YouTube on it, and after ignoring them for just 15 mins they’d have switched from whatever edutainment programme I’d put on to a video of a burly pair of hands unwrapping toys - for 4 hours...there are no studies on the long term effects of YouTube on cognitive development in young brains but why wait? It’s not like it’s rocket science to infer that if you show growing minds poor quality content you’re going to get poor quality results.
I don’t feel comfortable leaving my kids to watch Netflix either. It’s too easy for them to binge watch a half season of Paw Patrol or Omizumi or other similarly lite content. As a kid I remember eagerly waiting for the next episode of He-Man or Ghostbusters but to have had several seasons of dozens of episodes on tap would have been too much to resist. With auto play on these services too it’s not like they have the interests of us or our kids at heart.
We need to be super careful here, this is new territory with early indicators showing declines in ability to concentrate in adults from these forms of distraction - god knows what it’s doing to our kids.
