Lately he has been understanding possessions: dada brush (dad's toothbrush), mama shoes, baby juice. He refers to himself as Baby. If I ask him where Liam is, he points to himself and says "baby." Any other kid under 4 or so is also a baby according to him.
Yesterday, we played outside after a rain storm and he kept repeating "water voom, water voom." This is toddler for "the car is wet."
He also speaks a lot of jibberish that I don't understand yet.
Another funny story with a video to go along, Dan and I were shopping for ceiling fans. Dan called one of the fans sleek and I said "sleek???" Liam thought that was hilarious so he tried to say it too, but it came out "geek." We repeated it for a few days but it's still "sss-geek."
