There are also some physical skills that kids develop from learning to turn pages, and handle books.
Books and devices are going to be around for a long time. Kids who develop appropriate fluency with both are going to be in a better position to make sense of their world.
Your approach seems almost like saying never take a kid on a trip to the grand canyon or show them a picture or video of it, when you can read them a poem or stage an interpretive dance about the grand canyon instead.
We have just returned to the UK after three years in a small country that had hardly a bookshop, where we've been relying on ebooks.
First day in UK we took our 5yo to Hamleys (Toy Shop) and Foyles (book shop). It was a revelation to her. But I can't tell you how enthused we all were by the variety and quality of print books.
For me the ebook/interactive app doesn't really offer yet the immersive experience of print (especially for childrens books). Even for technical books/literature, I find it difficult to get wrapped up in an ebook (perhaps because there are so many distractions a swipe away).
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).
There are so many great books that are enjoyable for young and old alike. It will of course depend on your and your child's proclivities, but our favorites over the years have included: The Wizard of Oz books (all 12 volumes, some of which are quite dark, except Ozma's birthday; blech); The Ramayana (seriously); Winnie the Pooh; Stuart Little; Narnia; Hobbit; Sherlock Holmes; Agatha Christie (we read 60 of these together after she turned 7; her favorite is The Body in the Library); Hugo Cabret; The Golden Compass; Sea of Trolls; Treasure Island; Tripods; Wrinkle in Time; Earthsea Trilogy; LOTR; Rumpole of the Bailey; James Thurber; Lemony Snicket (esp. All the Wrong Questions). In addition, she has her own favorites that she's read alone to herself over the years.
She also reads many graphic novels, which have greatly influenced her own storytelling and art. She has loved Amulet, Flight, Delilah Dirk, In Real Life, The Silver Six, Ghostopolis, Bad Island, Zita the Space Girl, Drama, Sisters, Smile, Rapunzel's Revenge, Bone.
For reading aloud, I especially recommend Sherlock Holmes, Agatha Christie, and other crime/mystery books with 19th-century decorum. They expose the crime, puzzles, characters, and social dynamics, while leaving the explicit sex and violence off stage. (She can of course ask about anything she likes.)
I hope people will respond with their favorite out-loud reading books.
