Why doesn't baby brain make people smarter?

I've heard a lot of anecdotal evidence that when you're pregnant you get tired and sometimes forgetful. And it's a fact of life that new babies wake up at night a lot, waking up their parents and leaving them sleep-deprived, and everyone knows from firsthand experience that you don't think quite so clearly when sleep-deprived.

In my own observations of people dealing with pregnancy and new babies, the result seems to be that they lose a level of critical thinking. Where before they would go "Interesting article. I wonder if the assumptions are valid and broadly applicable? I wonder how this premise is affected by the economic stimulus? What are the environmental implications? Would this hold if the stock market crashes and interest rates skyrocket?" they now go "OMG, you GUYS! Check out this article, it is SO TRUE!"

Doesn't this strike you as poor design? Why make the people responsible for the most helpless of our young temporarily dumber? How is that good for the perpetuation of the species? Wouldn't it be far more sensible for pregnancy hormones to give your cognitive powers a boost?
