Third of Molly seven children?

This question is a bit tricky! It seems like it's asking for a specific child, but it doesn't give us enough information.

Here's why:

* "Third" can be interpreted in different ways. It could mean the third child born, the third oldest, or even the third youngest.

* We don't know the order of Molly's children. Maybe they're twins, or the oldest is a boy and the rest are girls.

To figure out who the "third" child is, we need more information about Molly's children.
