Title is correct. "Foreign", in terms of language, is a language not spoken typically in one's home country. Now, a home country only applies to a person after they've been born, which is not the case of the subjects of the article. But still, we can give a bit of leeway to the author, and just presume the home country of the unborn child, and so, interpret the concept of a "foreign language" correctly.

Have you ever noticed that every other adult is seemingly unable to comprehend what being a kid is like?

Languages are not the same as generic sounds to the human brain. Title is clickbaity but I also think it more or less communicates the point of the article

The point of the study was to see if just a small amount of language exposure would be enough for the unborn baby to start learning it. And the answer was yes.

For a native language, the unborn baby gets a lot of exposure. Only with a foreign language would an unborn baby get a small amount of exposure.

> All languages are foreign.

The babies are exposed to French the whole pregnancy and after, it's the foreign Hebrew/German they are testing for.

This is a meaningless comment.

The study is most likely bunk, but this nit pick is boring and wrong, they should have enough native French exposure already, it's the foreign language that matters.
