My best friend in high school was gifted in what I think of as gifted, in fact she should have given birth to my children not me. She didn't hide how smart she was, she also happened to be very pretty so guys didn't mind that she was twice as smart than they were. There was never a point when she blended, she always stood out - in a good way. So I think it depends on the child, is that child driven? more passive? I look at my 5 year old I can't imagine her ND peers catching up at any point. But she is a very driven child. I can see my 4 year old blending more just because she's more passive. Hope that helps:)
