Today

Nina likes to get lifted up on a leg. Today, I told her I would lift her up seven times, so I counted for each lift and Nina repeated. I said "One"
Nina said "One."
I said "Two."
Nina responded "Two."
...
I said "Seven."
Nina responded "Eight!" :D

Later during our post-dinner stroll, we asked Nina, "How old are you?"
She responded, "One"
and we replied "Two!"

This repeated about three more times until she realized that she should say "Two" also!
