Inertia

Lately I have noticed that if I rush somewhere, especially up or down stairs, my belly continues to blob along 

(yes, I coined that phrase myself) 

long after I have stopped moving.

Baby Inertia?

Baby inertia has made it very easy to tell where the [bulk of the] baby is...

*butt-dances in chair to stir up the womb*

Large mass baby is currently on my left side, with some movement on the right side.

(I'm assuming that's limbs, and not digestion, but it could go either way.)
