Pregnancy Brain: Fact Or Fiction?

Experts are now saying there is no such thing as "pregnancy brain."  I disagree!  When my wife was pregnant she was always doing silly things.  Once I came home and found a plate of food in the microwave - I asked my wife about it and she said "ooops that was supposed to be my lunch."  She had microwaved the food several hours before and completely forgot about it. Another time I found a bottle of Ranch Dressing in the cupboard where the glasses go. I remember watching her try to pour juice in to a cup and missing it entirely - she didn't realize she was spilling everywhere until she went to take a drink. Those are just a few examples of the "pregnancy brain" that I witnessed.  I'm sure you have stories too if you've ever been pregnant or been around a pregnant woman.
