Grover or Elmo?

Imagine my shock the last couple of weeks when Isabella has been pointing at pictures of Grover and clearly saying "Elmo". We do have a couple of Elmo books, but maybe she has picked up this Elmo thing at daycare.

However - today Isabella said "Grover" for the very first time. She was pointing at a stuffed Grover and saying "Elmo" and Jeff was correcting her and then she said clear as day "Grover"! Very exciting!
