Here is a conversation I had with my just turned three year old...
To set the scene she was sitting on my lap while I was sitting at the computer desk..
Caitlynn : "Mama why there 2 O's on this?"
Me : "on what?"
Caitlynn: " On this" (she points to the keyboard)
Me: "where are the 2 O's?"
Caitlynn then pointed to the O and the zero right above it.
Wow I had to try to explain that the zero was a number and the O was a letter....
To my little girl who just turned 3 two days ago...
She is such a little smarty :).
