When explaining something to a child, do you pay attention to your use of language?

I just observed a dad, interacting with his daughter. The girl was not yet two, I’d say, and determined to stay at the local bookstore. They have a small merry-go-round set up, as well as a slide and beanbags to read on.

The dad said,

“Come on, Sophie. I don’t know if you haven’t grasped the concept of a bookstore, but we go here to buy books. The merry-go-round won’t run away.”

The kid responded with an enthusiastic, “Merry-go-round!”. She had been listening, but was clearly not understanding most of her dad’s words.

When talking to a young child, do you consciously alter your way of speaking?
