while your eyes have probably gone bad from staring so much (LOL), I would have to say you were NOT imagining things. I do the same thing....I will yell to hubby, come quick, and he'll run, only to see me looking longingly into the bator. I will say, is one wiggiling, and he will be a dear and come look-see with me. he will sometimes see it, sometimes not, but always say yes. I think he would like to run away sometimes, LOL.
It is hard to tell if they wiggle....by the time you figure one just moved, you are trying to figure out if someone walked across the floor, you bumped the bator, or anything else like it. Then.....BAM! it happens again.
and you are glued to the bator for several more hours, waiting for the big day
