I am in the same boat as your girl. My DS turns 3 in 12 days and he is way above the bar and borderlines freakish at times. I understand your concerns and praise you for taking notice.
I also have a DD6 who is gifted, but she is easy going and quiet so no one ever notices that her brain is moving fast, but my 2yo is way more advanced and outspoken so I am beginning to worry about him.
I understand you girl!
My advice is
# 1 wait on the testing. You do not need a report to tell you when your child is gifted and it will be more accurate closer to school age.
# 2 Give your child all things they need to be happy and move forward at her pace.
# 3 It is never to early to statr looking into your school district and start laying the foundation for schooling. Some districts have schools for gifted and others have much to be desired.
I wish you luck and hope your keep posting here! We can worry together
This site is a great place to be yourself and be free to brag or cry. anytime.
