It’s not really about the screen at all. It is about the content. Schools use screens with educational content as a core teaching aid. The use is supervised throughout.
For our family the rule is no devices in bedrooms or any private areas of the house. There is a public homework space.
The way parents are spoken to about screen time can be negative. A local nursery said to parents in a leaflet “ Too much screen time can be damaging”. A strong, clear assertion but is it that simple? NO IT IS NOT.
As the nursery was told by an informed parent, “ if a toddler is left with a device to watch a series of Peppa Pig that is a very different experience to if they are using it to play colour matching, shape games, doing puzzles or learning how the universe was created” . In the Peppa Pig scenario we have a passive child. Devices should help a child think and interact.
