simply to have the brain be more active than passive and stimulate imagination.
But this is a free world and everyone to feel what they think is correct. Reading education and brain development materials could help deciding on what is good or not.
Parent of a 7yo and an almost 3yo with no TV at home, no computer time at all, and few iphone screen-time: only screen time is during long flights to Europe or somewhere else, road trips or when they are really sick. And the few screen time is always watching something in their second language (primary is English) as we're raising them bilingual. Again, this is our decision and this is a free world.
Why? because we feel that encouraging imagination development is key for their future as an adult being artistic or more technical. As adults we are constantly using our imagination for thinking out of the box, reaching far in our imagination for creating new solutions, etc.
No judging here and everyone can have is own point of view; and at the end who knows who is right or wrong? My only advice would be for the parents to educate themselves more on brain development and use their own judgement when reading such materials (often really opinionated).
