At first, you only liked pens.
Then coloring pencils.
Now, crayons. You got a set for Christmas and are really fond of them right now.
I love to hear you say the name of the color as you pull it out of the bag. "Oh, Purpup!"
We spent the morning coloring.
I love your face in this. This is a common expression and it is usually accompanied by an "Oh, yeah" headnod.
