I mentioned this to my cousin whose son insists on being read to multiple times a day. He’s 18 months old. She wanted to know if it still counts if it’s the same set of books, over and over. Because he is being read to many times a day, the number of books multiplies by that many more times. I think it doesn’t matter if it’s the same book. He’s still getting information and learning that letters mean words. It’s all learning. It’s also teaching him a love of reading. Before we know it, he’ll be reading on his own.
