One...Two...Three

Quite often, as I'm doing things with or for Marlee, I count. For example, I will say to her two books, one two. Tonight, as Marlee and I played before bed, I said one...and Marlee said two. I said three and she said four. I did this with her over and over to make sure I was hearing what I thought I was hearing.
Tonight I learned that, when prompted, my 19 month old daughter counts to five.
Amazing.
She is learning new things every day.
