Jack is starting to ask "What this?" a lot. It's really cute. He could be asking what the bat, spider and Count Dracula are on his pajama shirt or something else random around the house.
Also, Jack used to say "uh huh" a lot when he meant "yes." Now, he is saying, "Okay."
And speaking of random things, I took the top picture when Jack stacked his shoes on top of daddy's this week. That struck us as really cute.
