The second issue does touch on whether "they all even out." I don't think they do, but I don't think relative positions are fixed at 6 months or 6 years either. Katelyn'sM om, from your descriptions of your DD, if we lined up 100 kids at 12 months, my DS would have shown development in the bottom 5% and your DD would clearly be at the top. If we looked at them again at 2 years for just verbal development, my DS wouldn't be quite so low and your DD would still be amazing. By the time my DS took an IQ test at 6, it is impossible to score higher than he did verbally (without looking at extended scores), so he's changed relative positions a LOT. I believe that your DD will still be precocious and advanced at 4 or 8 or 12 or 20, but she might not have the same exact relative position since other kids are late-bloomers or slow to get started or on a different trajectory altogether. They don't all even out because someone is always in the 99th percentile on whatever measure! But I'm not sure that's always the kid one would have predicted from looking at 1 yo or 3 yo or 10 yo or 15 yo. I guess I see the asynchrony that most agree is common in HG kids as extending to development too. Just as a kid with capacity for abstract math can forget his lunch box nearly daily, another kid with incredible verbal capacity receptively can have relative delays in expressive capacity, or delays in motor development but not abstract concept formation, or just be a bit lazy in exploring his environment, or have a cautious personality that leads to observation rather than efforts at doing, etc.
Ultimately, I see Ruf's work as operating from a fixed theory of intelligence and I don't share that assumption. I think early milestones don't work because they assume that one snapshot in time predicts what kids look like at another snapshot in time. Watching my own kids develop, they do it so unevenly that their relative positions compared to other kids seem quite fluid. One of my kids suddenly made a giant leap in chess this year after a year or two of fairly lackluster development. Some kids work harder. Some have inadequate nutrition that hampers brain growth. Some learn more through self-motivated activity and develop their brains through cultural advantages, choosing to go to math camp, or ferocious learning to keep up with an older sib or share an interest of a parent. The nervous system continues to develop and change (and, sadly at my age, weaken

) over time in ways that don't seem fixed to me. An IQ test gives a one-day estimate that relies on performance of particular tasks as a substitute for what we think is intelligence and then assigns relative rank for performance on those tasks. It seems to me that those ranks would be subject to change over time, so it's hard for me to think that a kid could *be* a level 3 as an ongoing label starting literally from birth. Isn't that a little like saying that the best runner was the one that ran first as a toddler rather than evaluating this as an ongoing process?
