The Cutest Cookie Monster You've Ever Seen

So, we had dinner on the back porch on Saturday night because it was so pretty outside. Lily Kate finished off her dinner with a few Oreo cookies (thank to her Daddy!)...and here is what happened:

Thanks for the cookie, Dad!

Am I really allowed to eat this?
Don't mess with me and my cookie...
I can share, if you want to...

Who stole the cookie from the cookie jar?

If I sing a song, can I have another one?
La, la, la!
Please.
With sugar on top?
