Baby CP said that this is his "ban", which is short for "hua ban" which means skateboard. He has also been quite obsessed with pretending that a small pot with a handle is a guitar. It took me a while to figure out what he was doing when he was saying "jin jin jang!" over and over again while moving his hand over the handle. I guess he's got a good imagination.
Last night's conversation:
Baby CP: Ma ma!
Me: Dui, wo shi ni de mama. Ni shi shei? ("Yes, that's right, I'm your mom. Who are you?")
Baby CP: Dong Dong.
I think that's the first time he really understood that he was referring to himself.
