I didn't realize DD3.5 was atypical until about 18 to 20 months-old. A friend of mine pointed out that it wasn't typical for a child that age to know her colors. Then I told my friend the rest of it -- DD recognized all letters, numbers thru 9, knew many letter sounds, some sight words, etc. I thought it was because DD was so intense about me repeatedly reading to her, talking about the colors of the crayons and just interacting in general. She's my first-born so DH and I were quite naive about developmental milestones, especially since DD didn't start to take off until 18 months.
We used to get funny looks from my DB when DD would get on the computer by herself, launch the web browser, find her website in the drop-down menu and begin playing -- at age 2. At the time it seemed natural to me, but now that she's older and we have another DD16mo, I can't believe she was only 2 years old and using the computer by herself. The thought of it makes me chuckle because it seems so ridiculous.
Now DD3.5 is reading easy-readers all by herself without having ever seen the books before -- we're very proud! Her preschool teachers have been floored (I let them figure DD's abilities out on their own so I wouldn't sound like a crazy mom).
On the flip side, I'm a GT adult, but my DM does not tell stories about any unusual behavior from me before starting school. I was an easy-going child who always wanted to please. I didn't realize I was GT until I started reading up on all of this stuff. Go figure.
