Dd taught herself - she became interested at a couple of weeks past her 2nd birthday and taught herself the whole alphabet in 2 weeks. The next week she taught herself numbers. She learned upper case alphabet first and lower case was in week 4 or something, lol.
I was pretty stunned but she's the type who when she wants something, she does it, kwim? I say she "taught herself" because one day when we were looking at the *one* book she would sit still for 10 seconds for (because I made humorous animal noises), she pointed a the letter K and said, "K!". Suddenly she was pointing to letters and saying "Whazis? Whazis? Whazis?" relentlessly, 24/7, until she knew them all.
She's just voracious but it's always on her terms! Goodness forbid I attempt to "teach" her anything - hahahahaha!
She's 2y4mo now and is trying to write the letters - she can get a scrawl that looks sort of like a "C" or "M" and she'll point at it and exclaim what it is . . . sometimes you can't read them but I go along with her.

It was a relief to see her suddenly so interested in letters because she was 100% pure energy until 2 yo, a very physical toddler, and only had a few words. That changed very rapidly after she turned 2.
