"In English, we adults like to say babies go "goo goo ga ga." In French, it's "areau areau." And in Mandarin, it's "ya ya."

So do babies really babble with different sounds in different parts of the world? And what does that tell us about how babies learn to speak?

A few years ago I was on a train, seated across a table from a French woman traveling with her toddler.

His mom and I hit it off and spoke in English for a few hours. Meanwhile, this little boy had a lot to say. I couldn't understand it, but he clearly had opinions about his books, his snacks, maybe how cool it was that his hands were attached to his arms – all in what I just assumed was French".
