What Dora's good for

Guess who learned how to count to 10 and has done so repeatedly today?? Even now, when she's supposed to be napping, I can hear her up there counting loudly to baby Lila.  I guess Dora is good for something.....Not that a 2-year-old needs to be able to count to 10 and frankly, I'd rather she not know how to count than watch as much Dora as she has been, but still, I must admit that I'm impressed and close to proclaiming her a genius and sending in a recommendation to Mensa that they admit Hannah as the newest member of their genius club.
