Learning on the Sly

In preparing to make my traditional birthday apple pie, I took out the bag of apples to count how many were left.  I need at least 9 to make a good pie, and these are rather small, so more is better.  With Maddie sitting at the table enjoying her lunch, I began pulling apples from the bag and placing them on the table as I counted.

"One," I said.
"Two!" Maddie chimed in.  This is no surprise, since we frequently count her arms, legs, shoes, eyes and other pairs of items.
"Three," I continued.
"Fo!" Maddie yelled.
"Five," I said.
"Sick!"
"Seven."
"A!"
"Ni!"
"Ten!"
"Eleven."
"Twe!"

It seems she's been listening to all those number songs I sing after all!
