Baby seems to have unusually good memory at 11 months?

Maybe I’m not around a lot of other babies, but I feel like my son has a crazy good memory for 11 months old. Today I read him a new book (Pat the Bunny if anyone’s familiar). We went through each page- pat the bunny, smell the flowers, peekaboo etc and then he took a nap. When he woke up, he crawled back to the book so I read it to him again. As soon as I turned the pages, he would do the action on each page. Like he smelled the flowers before me reading to tell him to smell the flowers. This is today’s examples. He’s also able to point to several different items by name when I’ve told him what each was called once or twice. Do other 11 month olds do this or is he some sort of wizard!?
