Welcome! My son started sounding out words without any prompting at 2 1/2 and was reading easy readers by 3. I started following this forum right around then, trying to figure out what it all meant and what, if anything, I needed to do about it. The information I got here gave me the sense to find a school that would "get" him and the courage to skip pre-K and go straight to kindergarten. He's now 4 going on 5, reading at at least the 5th grade level, and absolutely loving big-boy school. So, no, in my opinion, reading at 3 is not normal, but it doesn't have to be scary either!
