I found this statistic on the adhesive protector from a sanitary napkin: "When a woman is pregnant, her uterus expands to 500 times its normal size." (See photo from March 30 - you'll be convinced.)
And, while Zupe at birth weighed only about 6% of my weight, he was over 34% as tall as I am! Of course, that 54 centimeters wasn't stretched out in my abdomen, but curled up in what is so appropriately called The Fetal Position. In the photo above Zupe is a bit more than 1 week old. He's actually lighter than he was at birth - so this is mini-Zupe.
I knew that and I knew he was head down for the last 4 to 6 weeks. But, it wasn't until he was born and I was looking at his body that I understood that the "foot" I was always shifting off my midline was more likely a knee. I never even considered that I was being "elbowed" by elbows and knees. I was only thinking about hands and feet (while still puzzling over why his feet would be so low - just under my umbilicus. Perhaps I spend too much time looking at and thinking about dog feet?)
OMG - this is so funny - I just looked at that photo and thought, wow! he was so little. That didn't take long!
