As long as she is happy. Gifted kids can sometimes lack friends since they are different. But many gifted kids still have friends and a social life. As long as other parts of her life work, I would not worry. Just make sure she has access to mental stimulation, being smart means you can also get bored. And if you don't have to work for progress it might happen you never truly learn how to study things that are a bit harder for you. I was never gifted to that point but the first grades I didn't have to make any efforts, that meant that I never learned to study "their way". And when it was finally necessary, I didn't know how to. So don't forget to have her do "boring" things also.
