I *might* have felt the baby moving/kicking last night at pre-natal yoga. Not sure. I was lying on my back with my knees pulled into my chest, rocking from side to side, and there was a definite 'reaction' from my insides. Not a flutter or a bubble or a butterfly or popcorn - I would best describe it as a "splort".
I guess I'd have to feel it about 20 more times before I could definitively say it's the baby (or not the baby), but in the meantime it sure is nice to feel something.
