I started a collection of about six or so realistic looking vehicles in an effort to begin building familiarity with them. I wanted her to start making a connection to the real thing as we see them around town. Yumi’s current favorite is by far the firetruck. She enjoys the added element of extending the ladder. So much so that she pulled it off! So there’s that. Also, some of them have the wind up/pull back feature and go without a push, which she’s figuring out now too.
