She sure is gifted, knowing 100 sight words isn't exactly your ND almost 2 year old
Enjoy the ride. Let her show you what she wants to do. Forget all the toy age limits or what other people think is appropriate at this age and do what feels right.
She may be ready for a simple reading or other educational computer games (I personally prefer Reader Rabbit or try starfall.com). You may need to help her navigate the computer but she can give you all the answers.
Read to her about whatever she likes, take her to Zoo, museums, music classes, ...My older one liked PreK workbooks such as recognizing same and different pictures and such.
