I fight it as long as I can. The waddle. I mean, you can't strut when pregnant, but you can aim to look as less duck like as possible for as long as possible. But... then... inevitably... it becomes out of your control. You feel it in every inch of your movement, you see it on people's faces, you catch yourself in reflective windows - your waddling!
*waddle waddle pant pant waddle waddle pant* Somewhere between 6 and 8 months pregnant you stopped being a woman and became a duck-dog!
Don't worry it's only temporary.
