"Point to Your Nose"

As most other parents of 14-month olds are doing, we've been working with Logan on pointing to his eyes, hair, ears, etc. He's done really well with it over the last several months until the last couple weeks when we say, "Point to your nose," and he just picks his nose. I tell him again, "No, POINT to your nose," and he just picks deeper! I'm convinced that Jason taught him this sometime when I wasn't around, but he continues to deny it. We'll keep working with him but I am really hoping this one is just a phase!
