Why not? My 26mo has been able to draw circles for a while now and also is aware that a circle is a zero and the letter "o" so I don't see why some kids wouldn't figure out writing at that age, especially if they spend a lot of time drawing. She surprised me the other day when she was doing a number puzzle at the chiropractor's and I would ask what each one was that she picked up - when it got to 4 she kept saying "cot", and it took me a few minutes to realize she was saying it in French (quatre)! LOL I had to count it out in my head to even figure it out but she knew right away!!
