I think she's saying "huh?"

 Sophia shocked me yesterday with all of the new things that she was doing, but shocked me even more today.  She has learned how to scoot.....but only scoots backwards!  Hey, whatever works to get her where she wants to go :o)   She can also all of a sudden get up on her hands and knees.  She also has another tooth that popped through, so she now has 3 on top and 2 on the bottom.
