How Fast Time Flies

Big news in our house last night:  La Nina lost her first tooth.  I remember her showing off that tooth so clearly in China.  She had it longer than she's had us. 

And now, she's showing off the place where it used to be.  Was it just yesterday I was trying to figure out how to help her cut these teeth?  And now, the process of them falling out has begun.  Isn't that classic motherhood?  All my worry and stress, and the darn things fall out anyway.
