I want to get my toddlers IQ tested - how would I do that?

My daughter is 2 1/2 years old. She speaks in full sentances and her comprehension is phenominal. Just yesterday she corrected her own grammer. She is doing better with her colors and numbers than any other child of her age I have seen. But, maybe I've only known dumb kids? Lol. I would just like to see if she has some extra potential that I should be encouraging more than what I do. I want her to have every advantage if she can do it, and wants it. I mean I'm not going to push her too hard and then parade her around as I've seen done...I'm just kinda curious.
