“I’m coloring the k”

Falyn was coloring in her princess sticker book when she told me, “I’m coloring the k”. She then pointed to the “k” and said, “See, there is a k right there.” I looked and sure enough, there was a “k” in the word “book” that she was coloring. I pointed to the “oo”s and asked her what letter they were and she said, “Those are o’s”. I guess she has been picking up letters from her older siblings.
