Baby brain

I've heard women can become forgetful during pregnancy (afterwards as well?).  Not sure if I can blame it on the baby, but the other day at the end of brunch it was time to pay the bill.  I look through my purse and can't find my wallet, check my jacket pocket, check my purse again.  Mention to D, that he may have to pay for us, when I notice that my wallet is open right in front of me on the table--I had already pulled it out of my purse and just needed to grab my credit card.  A few days later, we're heading out to the car, I'm looking for my keys in my purse, then in my pocket, ummmm yeah, my keys are in my hand.  Maybe I'll just blame these instances on a full belly and lack of sleep, respectively.
