He has a memory like a steel trap. Especially if it rhymes or is set to a melody. I think he knows the lyrics to every song he's ever heard. Learning the alphabet song was a cinch. We read a book to him a few times and then he'll start reading it to us. Strangers are shocked that he just turned 2 because he knows so many words.
I don't think I can take much credit for how fast he learns, but I love it and only hope I can keep up with him.
Nolan doesn't do much yet, haha, but he sure looks cute while he sleeps :)
