Adventures in Potty Training: De-Diapering

So the kids have both taken their diapers off before.  But Addison has reprised this ability and for the last few days has started showing off her de-diapering skills.  We're talking ten times in an afternoon.  Quick like.  Silent.  Even after we put shorts on her.  Sometimes I'll find her reading without pants.  Other times, I'll find her sitting in the yellow plastic shopping basket and saying, "Tinkulliiiiing".  She isn't really (yet!) but it's only a matter of time.  Perhaps this is a positive step?  Another little independence that gets us a tiny bit closer to the day when Addison going to bathroom won't involve me at all.  Of course, it could also be that she's doing it just because she can.  Oh please, oh please, let's hope that Caden doesn't follow suit...
