Sometimes when I sit very still and pay close attention, I think I can feel Bart moving. This started yesterday and I'm almost positive it's not just gas. It feels like one of the following is happening:
1. A very tiny leprechaun is gently knocking on the wall of my uterus from inside.
2. A fat butterfly with strong wings is fluttering around in there.
3. Really faint gas bubbles are popping and shifting, but lower. And weirder.
