That's a big yes. I saw signs with DD5 as early as 10-12 months. This is when I started playing with foam letters in the bathtub with her. Once she started learning her ABC's she had to play that game every night until she knew all the letters, which she did before 12 months. She is like this with everything she learns, when she starts something she does it over, and over, and over til she is at a point she's happy that she knows it well.
