As I said before, I'm pleased that he likes books and being read to. He has been known to "read" by himself:

I don't really care whether he prefers paper or electronic books. I decided to try him with an e-book because if he was happy with them, then I could make sure that I always had one on my phone and Kindle, and would thus always have a book that I could read to him. If we go anywhere we usually take books, but I thought it might be useful to always have a "standby" for unexpected situations.
I shared the story because I thought others might find it interesting.
