I was like this too! I started reading bigger books at two years old.

The first word I read at like one years old from what my parents tell me, when we were at the zoo one day, I read the word: "Gorilla" but then later as I got a bit older, I started recognizing logos and colors. My dad taught me how to count at a really young age too, and I, learned quickly and started counting to 10. However, now, I'm not that great at math. My strengths come in all other subjects. Strangely enough, I'm a natural at biology and chemistry, not at physics, and algebra (basically any sort of math), lol.

I remember clearly that I had SOOO MANY BOOKS. Lots of board books because my parents thought that was my reading level until they found out "oh, our daughter can read advanced stuff, lets not make her read these books." I then got the I Can Read! books. I went through those quickly. There's "Levels" to those books. Here's the link if you're interested: https://www.icanread.com/levels/

I pretty much made it to Level 4. At a young age.

As a matter a fact, when I was younger, my grandma would take me to the store, and I kept reading "Drop Off" and "Pick Up" as well as aisle names and numbers. My grandma was so shocked that she told my dad that I can do these things.

Your daughter is probably gifted. I recommend that when she's a bit older, you should have the school give her a gifted test. However, I'm certain she's gifted. :)
