My little one is quite active as well, i never need to monitor her movements as she's at it all day, i know what you mean JoMarie with the "sweeping" movement, i get this alot at night, i find it quiet painfull sometimes though. She was head down but on her side to me last time i went to the MW.
My "HUGE" movement is it feels as if shes jumping around in there! (party girl!) I get this kind of a "thud" feeling and this also hurts. (my DD tell's me that she "loosened" it up in there for her!)
Strange question to ask though, as my answer would be "yes, all the time!"
