+# Who Is Your Favorite Child?
+
+When we put some content inside the open and close tags of one of our
+components, we get access to it as the `children` prop.
+
+```javascript
+const Parent = ({children}) => {
+  return (
+    <React.Fragment>
+      <p>These are my favorites:</p>
+      {children}
+    </React.Fragment>
+  );
+}
+
+const App = () => (
+  <div>
+    <Parent>
+      Greg and Marsha
+    </Parent>
+  </div>
+);
+```
+
+What happens if we also provide an explicit `children` prop to `Parent`?
+
+```javascript
+const App = () => (
+  <div>
+    <Parent children={"Jan and Peter"}>
+      Greg and Marsha
+    </Parent>
+  </div>
+);
+```
+
+Which will take precedence when we destructure `children` in the parent
+component?
+
+In the example above, we'll still see `Greg and Marsha` rendered. The
+content placed inside the tags will take precedence over the explicit
+`children` prop.
