Just to preface this - we are not the type of parents that thinks everything that our 3 y.o. DS does is special. Occasionally he'll do something silly and we whisper to each other "no scholarship for him!". But he's currently doing something that to us seems pretty smart. We're just wondering if its normal or maybe advanced.
DS loves all of my old Golden Books. Especially one called The Wonderful School. Most of these books are around 16 or so pages. After we read one a few times DS can go thru the book page by page and "read" them to us. He doesnt miss a word. He can do this with at least a dozen books. Clearly he's just memorizing them, but he memorizes them so very fast. Is this normal? I don't feel comfortable asking any other parents IRL because I don't want to compare my child to his friends. I don't think my DS is better than anyone else. I'm just curious.
I really hope I don't get flamed for this.

Many children who are read to often have the knack for memorizing/"reading" favorite stories on their own. My own DS(2) does the same thing with many of his books. And you're absolutely right, it doesn't take long for them to memorize it. He usually starts by just recalling when to turn the pages for me while I read it and before I know it he's sitting down to "read" the story to his "friends" (pooh bear and ernie
). It really is adorable to listen to him too - I crack up almost every time he gets to the end of the book "Olivia" when the little pig is bargaining with her mom about how many books to read before bed - too funny and he never misses a word!
