Myth: Babies who walk early and talk early are the brightest of their peer group.
Truth: Earlier-than-average talking and walking skills are meaningless in the big race of life, says Susan Anderson Swedo, M.D. "The bottom line is that children who are significantly delayed in these areas may have lingering problems, but the opposite is not true," she says.
In fact, she notes, those highly noticeable developmental milestones are merely a function of motor development: Just as you can't walk until you learn to crawl (usually), you can't talk until you learn to manipulate your mouth. Both require the miracle of normal nerve growth, which will occur in each child at its own pace, soaring IQ or no soaring IQ.
