I guess I a still having problems with this. It's hard to really wrap my head around the things DD is doing that aren't normal. At 2.5 she recognizes all letters Upper and Lower case, can match them, knows their sounds, can do beginning and ending letters in words, counts everything, and not just rote counting like most kids her age, but actually counting. I never realized it wasn't normal for kids not know most colors by 18 months, or that apparently most kids don't know the difference between pink and purple until around 4....she has known this since well before 2. She's alreading is writing most letters, recognizes site words.
I guess one thing that happened really early, that at the time I assumed was normal.....I can't remember exactly when, but it was sometime after 12 months, but before 18 months, DD began memorizing entire books.... these were short board books, but after reading them once to hr she woulld memorize the entire thing. Now at 2.5 she memorizes books with over 500 words after hearing them only twice.
She also while not reading yet, completely surprises us by "reading" signs. She obviously recognizes words. The other day we placed an icecream place that has been closed for a long time. We have never been there. There sign is still up. And DD knew we were going for icecream and asked if we were going to that ice cream place as we got near it.....It had no pics or anything around to help associate, it jut said xxxxxxx icecream. DH and I were both floored.
