Here is that video of Addison counting that I talked about forever ago. She can count from 1 to 12 and even says 13 and 14 now (though does not count 1-14, if that makes sense).
She counts to 10 in this one, but it's barely audible, so turn your volume up! Oh, and please note she says "sixen" for "six". I think that's because it precedes seven and she relates the two.
This video is a little louder, but she stops at 8 and needs some help getting 9 and 10 out, as she gets distracted by the fish on her plate.
