Freeze Crawl

Cami fully understands the phrase "no no."  She fully understands many phrases (some quite complicated, like "why don't you take your soccer ball through your tunnel?"....what???), but sometimes I wonder if her compliance with what I ask her to do is coincidence.  But, I know she knows what no no means because she is fairly good a stopping what she is doing and turning to look at me.  However, she has a new response, the freeze crawl.  In this response, I say "no no, Cami."  Mid-stride, she completely freezes.  Then s-l-o-w-l-y continues her motion towards whatever she is trying to get.  I say "no no" again and get a freeze....but a shorter one until the molasses crawl begins again.  I think she thinks I'm not going to notice she's moving if she does it really slowly.  I suppose the freeze crawl is better than the times she stops, looks at me, smiles, and does whatever I told her not to do anyway.....
