i'm not sure it's any sort of sign. dd got pretty squirmy for her last few weeks, and this one's been doing the same. i'm guessing they're just trying to get comfy since space is limited, and it's just a bit harder now. i've been doing lots of hands and knees time as well as an inversion every day, just to make sure everything's evened out in my body. my MW also reccomends to skip a step when you're walking up them to even out ligaments and whatnot. hth! oh and the "whack-a-mole" thing cracked me up! my LO has been trying out a posterior position on and off for the past week, and it's so uncomfortable!
