Teeth

G has her first mobile tooth - lower left central (o). 
Also, #19 is partially erupted (November).

At some point, when I have time, I will go back and see if tooth o erupted first or p.  My theory - you exfoliate the teeth in the order they erupted.  I'm going to test it on my sample size of 2 (twins already had their teeth before arriving - except 2nd primary molars).

This is the dental geek in me.  OK. Enough.
