Quality Over Quantity
Emerging research has indicated that the quality of screen-based activities should guide the quantity of screen time.
As a parent, it's important to stay aware of the type of activities your kids are participating in online, so you can make informed choices about screen-time limits. The simple rule here is that anything that has more quality to it (either it's educational or is a socially shared activity such as watching a family movie) can render more quantity (time), whereas a screen-based activity that isn't quality, means a little less quantity.
Think of it this way - The Bachelor is an entertaining show, but doesn't provide much educational value. It doesn't do any harm to watch a small amount, but binge watching it for 5 hours might not be doing our brain (or body) any favours!
