"Knock-knock"
"Who's there?"
"Elmo!"
"Elmo who?"
"Abbie!"
Basically, the punchline (which is always nonsensical) always changes, and sometimes (like in the video below) is non-existent because she just cracks herself up at the thought of how funny it all is.
She is also doing a great job with her words. In the photo below, she put these blocks on her wrists and then said, "bracelets". When I was talking this morning about how much older she seems, she said "exciting". I'm just never sure what is going to pop out of her mouth. This past weekend, she surprised me by saying, "changed my mind." Last week I was wearing some pants that I hadn't worn in awhile and she surprised me by saying, "new pants!"
Of course, when she is having a two-year old moment it can be quite dramatic. When she feels frustrated by something she will cry and refuses to let anyone comfort her. She will cry and say, "No, no, no, no, no, no!" If you approach her she'll yell, "away, away!" Of course, if you go too far away then she will cry for you to come back.
She has also figured out how to go boneless if you pick her up when she doesn't want to be picked up. This past Saturday, Chad got her out of the car, but she didn't want to be held and didn't want to go inside. She went limp and he just laid her down on the mat outside the door. We just stepped over her as we unloaded groceries, etc. and she was happy as a clam to have succeeded at not going inside.
I think that ultimately I needed her to come inside for a nap, so I had to pick her up and bring her in, which made her mad, of course. Poor little thing.
