John Hawks has a two-year-old. And I agree with him --- two year olds are not Neandertals, whatever else they may be. Heck, even Neandertal two year olds probably weren't "Neandertals", though they doubtless wore their parents out! I don't think things have changed that much in 40,000 years. But Harvey Karp, author of a parenting book called The Happiest Toddler On the Block, which came out about four years ago, seems to think otherwise. Really, I don't know why people think later "archaic" humans were all that different from "us", or more "childlike" or whatever. I thought this kind of thinking went out with the 19th century. But apparently I was mistaken, even if, as Dr. Hawks suggests, the guy's parenting advice is perfectly good.
Note: This is a sort of disclaimer. Having parented a two year old myself once upon a time, I can understand the temptation, but no, I repeat: two year olds are not Neandertals!
