Going Batty for Baby: The Signs of Mommy Brain

Einstein said that "the definition of insanity is doing the same thing over and over again and expecting different results"...so when exactly is it that mothers go insane?  I mean, how many times will I continue to pick up the toy and hand it back to him only to have him throw it back onto the floor?  Four?  Five? Six times before I'm deemed insane?  How many times will it take for me to realize that he's going to kick his socks off no matter how much I say "keep your socks on man"?  I find myself having full on conversations with him while pushing him in his stroller through the mall.  His sporatic responses of "dada", "baba", and high pitched squealing are enough to keep me enthralled by "shared" dialogue of reduced prices and cute shoes.  Sometimes I catch myself and wonder what it must look like to people to see a woman discussing markups with an infant.  Our most recent deep conversation was about my taxes and whether or not my move to Georgia was deductible.  Why have I been reduced to trusting a 6 month old with my tax return?  When I was pregnant I talked to him all of the time, so I guess it doesn't matter much to me now that his babble is a little less than thought provoking.  I'm just glad that he responds at all!
