Alex’s current favorite word is “Choo choo” (this makes his word total around five). He uses this to describe any loud engine (plane, train, motorcycle, bus, big truck, etc) or siren. It all started when we would play in the yard and I would point out a plane in the sky. Then he started pointing in the sky for any loud engine sound. When we heard a train, I tried to teach him that they weren’t all in the sky and worked on the word “choo choo”. Now he says “choo choo” and points in the sky for all loud engines. He’ll get it eventually…..
