Lip Smack-a-Lack-in'

With this most recent round of sickness/teething/whatever-it-is, June has found a favorite new skill:  smacking her lips.  She does it all the time, although she does it most in her highchair.  However, I don't think it really means anything (maybe it feels good on her gums?), since she often won't take a bite once she has gotten to lip-smacking.  :)  She thinks it is pretty funny when we do it with her, too.
