we've got a wiggler

Of the dental variety that is.  It came as a shock to me that Naiya has her first loose tooth!  I generally think of seven as "the change of teeth" and here we are with a wee five and three quarter year old with one bottom tooth a wigglin'.  I told her to stop messing with it (secretly hoping that the thing would maybe harden back into her gums). 
I'm not ready for the loosing of teeth.  (Am I the only one finding this aging of my child so disconcerting?)
My baby girl is growing up.
